4. How to Adjust Development Parameter

Use the "Parameter control" to adjust development parameters. By default, the "Parameter control" appears at the left side of the screen. You can move its position to the right side with [Display Setting].
Furthermore, you can change it to a floating window with the [Display setting].
On the "Parameter control", there are the following 3 sections;

(1) "Main control section" consists of some dropdown lists to select a taste (=preset value) and the "Exposure bias" slider control.

(2) "Tab page" is an area for the sub-controls, which are selected on the "Parameter control".

(3) "Control box" is an area for other sub-controls, which are used to adjust an image in even more detail by setting specified values.

The "sub-control", located on "Tab page" or "Control box", is a control for selecting a value in each category of the development parameters. The sub-control can be displayed also as a floating window.
You can specify the setting of "Parameter control" by [Display setting], which appeares on the menu command [View(V)]-[Display setting].
And you can specify the setting by a right-click upon the title area.

As a basic workflow, first set the level of the Exposure bias with "Slider control", then select each "taste" for white balance, tone, color, and sharpness/noise reduction.

4.1. "Parameter Control" and "Sub-control"


Parameter control has 3 sections. On the "Main control section" that is the top section, there are the following controls;

Taste/parameter (Dropdown list + Select button)
Exposure bias and HDR / dodging (Slider control)
White balance (Dropdown list + Select button)
Tone (Dropdown list + Select button)
Color (Dropdown list + Select button)
Sharpness/Noise reduction(Dropdown list + Select button)
Development (Select button)

On the bottom area of the "Parameter control", there are 8 buttons to switch sub-controls that are for fine adjustment of the development parameter or displaying information.

The dropdown list is the GUI for selecting a taste (=preset value) that is prepared in advance by ISL (Ichikawa Soft Laboratory) or a user.
The "taste" is a value consisting of development parameters. For more details about the "taste", please refer to '4.1.1 Taste'.
When you select a taste from the dropdown list, the related sub-controls automatically appear on the "Tab page". However, according to customer's preference, the sub-controls can be located on the "Control box" or a floating window.

4.1.1. Taste

Taste is a preset value , like a collection of development parameters.
You can easily define a "taste" value for frequently-used development parameters.

(1) Utilize maker tastes
Model development parameters are recorded in advance in SILKYPIX as maker tastes.
You can use these to easily make adjustments to development parameters.

Open the dropdown list and select a "Taste" to apply. By doing so, the development parameter registered in tastes will be reflected.
There are both "Overall tastes" to replace all development parameters and "Partial tastes" for a set of part of the development parameters found in tastes.
Applying "Partial tastes" is an action equivalent to "Partial paste of development parameters."

(2) Register development parameters often used as user tastes
Register development parameters which are used often can be saved as user tastes, making them easier to recall.
There are two ways to register to tastes, "All category tastes" for all development parameters, and other tastes registered as category units in development parameters.
Please refer to "4.1.1.3. Registering tastes" concerning how to register.

4.1.1.1. All category tastes

The dropdown list of "All category tastes" located to the side of the img/ico_taste04.jpg icon at the very top of the main control section in parameter controls will be explained here.
Tastes that can be selected here are all category tastes intended as "All categories" of development parameters.

There are two kinds of tastes, "Overall tastes" and "Partial tastes" in "All category tastes."

[Explanation of Display]



(1) (1) "The emphasized word with a under line" means default "taste". If the default "taste" is assigned from the existing "taste", the name of the existing taste is emphasized. If the default "taste" is not assigned from the existing "taste", the word "Default" is emphasized as shown on the explanation figure.
(2) ./img/ico_taste01.jpg indicates that this taste is in "Overall tastes."
If "Overall tastes" is selected, all categories of development parameters will be replaced.
(3) ./img/ico_taste02.jpg indicates that this taste is in "Partial tastes."
If "Partial tastes" is selected, only a part of the categories of development parameters will be replaced.
(4) The ./img/ico_taste02.jpg mark indicates that this taste is currently selected. If "Overall tastes," one will be marked, and if "Partial tastes," all that conform will be marked.

[Taste list for selection]

When you open the dropdown list, you can see and select the tastes on the list.


There are two kinds of tastes, one is "maker taste" prepared by ISL and the other is "user taste" defined by user.
And you can find "Default" and "Manual" on the list, which are not "tastes". They have the following meanings;



DefaultIf you select it, the development parameters are reset to default. When you specified one of tastes as default, the word "Default" is not displayed on the list. In this case, the name of the specified taste is emphasized.
ManualManual is displayed when the current taste does not match other existing tastes or the default taste.
Even if you select this taste, the development parameters will not be changed.



[Display of the selected taste]

When the dropdown list is closed, the name of the current taste is displayed.


When one of registered tastes is selected, the name of the selected taste is displayed.
The name of a partial taste is not displayed. Instead, "Default" or "Manual" is displayed.



Default Default is displayed when the development parameters of the current taste match those of the default.
Manual This indicates that neither results of adjusted development parameters nor registered tastes are in agreement.
Manual(Taste applied)Manual (Taste applied) is displayed when the development parameters of the current taste match those of a certain "partial taste".



*Partial taste is not displayed because the development parameters of the current taste can match those of two or more partial tastes at the same time. The mark of the "Partial taste" is displayed only when the dropdown list is opened.

4.1.1.2. Other tastes

The following will explain dropdown lists of tastes other than "All category tastes."



Dropdown lists for these tastes are located in the main control and at the top of each sub-control.
Dropdown lists, except for "All category tastes" located in the main control section, are, in order from the top:

[White Balance Taste]
[Tone Taste]
[Color Taste]
[Sharpness/Noise Reduction Taste]

When the sub-controls "White balance," "Tone," "Color," "Sharpness" and "Noise reduction" are displayed as floating windows, these dropdown lists will have the following in common with dropdown lists located at the top of each sub-control.



(1) [Target parameter category]
These dropdown lists are used to select partial tastes for only one parameter category.



If a taste other than "All category taste" located in the main control section is selected from a dropdown list, only development parameters that can be adjusted by the sub-control displayed on the tab page will be influenced.



If a taste is selected from these dropdown lists located at the top of the sub-control, only the development parameter that can be adjusted by the same sub-control (*1) will be influenced.

*1 But Sharp/noise reduction control is an exception. Its sub-controls are divided to two parts despite one parameter category.

(2) Taste list for selection
When you open the dropdown list, you can see and select the tastes on the list. There are two kinds of tastes, one is "maker taste" prepared by ISL and the other is "user taste" defined by user.


And you can find "Default" and "Manual" on the list, which are not "taste". have the following meanings;





Default If you select it, the development parameters are reset to default. When one of the existing tastes matches the default taste, the word "Default" is not displayed on the list. In this case, the name of the matched taste is emphasized.
Manual Manual is displayed when the current taste does not match other existing tastes or the default taste. Even if you select this taste, the development parameters will not be changed.
(2) Display of the selected taste
When dropdown list is closed, the name of the current taste is displayed.
When one of registered tastes is selected, the name of the selected taste is displayed. But the name of a partial taste is not displayed.


Otherwise, "Default" or "Manual" is sometimes displayed.





Default Default is displayed when the development parameters of the current taste match those of the default.
Manual This indicates the status that the results of adjusted development parameters are not in agreement with any of the registered tastes.

4.1.1.3. Adding Taste

You can add / register a development parameter applied to a currently selected scene as a taste.

There are two ways to add / register a taste. Select [Taste category] from [Parameter (P)] – [Register taste] on the menu, or click on the img/ico_taste06.jpg icon located on the right side of the dropdown list.
The "Taste registration" dialog will be displayed.
The "Taste registration" dialog format is the same as the "Edit taste" dialog. Please see the next section, "4.1.1.4. Editing tastes" concerning operation methods for this dialog.

"Tastes" added through the "Taste registration" dialog will be displayed in dialogs as selected, so set an appropriate name for the taste and click on the [OK] button to confirm.

Items set in the "Taste registration" dialog

(1) Taste name


By default, names are set sequentially, such as "User taste 1."


Change to an appropriate name to make it easy to distinguish from other tastes.

(2) Applicable development parameter category
If "Taste category" is added as a taste other than "All categories," it is not necessary to edit because "Applicable development parameter category" is fixed to one category.

If the "Taste category" is "All categories," you can enable any category in "Applicable development parameter category."
Enabled categories are set as taste masks.

4.1.1.4. Customizing Taste

You can edit registered tastes.
You can customize by changing taste names and the order they are displayed to make it easier to select tastes.
You can also save / restore tastes and move then to other PCs through export and import functions

"Taste registration" is performed from [Parameter (P)] – [Taste registration] on the menu.



(1) Subject data A taste is defined for a "RAW image" or a "JPEG/TIFF image". You can select either of the two types.
(2) Taste category A taste is defined for each parameter category.
(3) List of tastes There is a list of tastes with a mark.
A mark at the left of a taste title:
./img/ico_taste01.jpgThe taste represents all development parameters if you select taste category "All parameters".
./img/ico_taste02.jpgThe taste only part of the parameters if you select taste category "All parameters".

There are two kinds of tastes, maker tastes created in advance by our company, and user tastes that you create.

Maker taste
These are displayed with a red background. They cannot be deleted, exported or moved.

User taste
These are displayed with a green background.

(4) Upward button The upward button moves a selected taste upward.
(5) Downward button The downward button moves a selected taste downward.
(6) Hide button
/Display
Selected data is hidden.
Maker data cannot be deleted, but they will not be displayed on the list of tastes with this setting.
(7) Rename Change the name of selected tastes.
(8) Delete button The Delete button deletes selected tastes. Maker tastes cannot be deleted.
(9) Export all button All user tastes that have "Type of data" and "Type of taste" in common are recorded and saved in a file.
All tastes displayed with a green background are "Tastes that can be edited."
(10) Export button The export button exports a single selected taste.
(11) Import button The import button imports a saved taste.
(12) Parameter category to be applied When you select the "All parameters" in the list of the taste category, you can apply any of the parameter categories to a taste.
For example, you can apply "tone" and "tone curve" to a taste.

When you add a new taste, the "Customize taste" dialog is also displayed and you can customize a name of a new taste and other settings as well as the taste customizing.

4.1.1.5. Applying Tastes to Multiple Scenes

You can apply a taste to multiple scenes at the same time. In the "thumbnail mode" or "combination mode", when you select multiple scenes at the same time, the icon on the right side of the dropdown list changes to./img/ico_taste03.jpg.
When you click this icon, the taste list opens. Select one taste to apply and click "OK", then the selected taste will be applied to all selected scenes.

* If you selected many scenes at the same time, it may take some time for processing.


4.1.2. How to Operate GUI

You can perform taste registration and editing, save development parameters, read, initialize and temporarily register in the "Taste parameter" sub-control.


4.1.2.1. Cloakroom

The "Cloakroom" is a function that temporarily records development parameters.
There are four rooms (ROOM 1~4) in which you can record development parameters. There is also a special room named "Latest."

You can record optional development parameters in the first four rooms. Development parameters for the currently selected scene are recorded in a room by clicking the o button on the left side.
When development parameters are recorded in a room, the time they were recorded is displayed.
Rooms with recorded development parameters are turned into buttons, and when you click this button, the development parameters recorded in the room are pasted onto the currently selected scene.
In this way, you can copy development parameters from other scenes and past development parameters from the same scene.

Rooms with recorded development parameters that match the development parameters of the currently selected scene are displayed in bold.

The img/ico_paracopy.jpg icon on the right side is a button for entering "Continual copy mode." "Continual copy mode" is a mode for pasting development parameters recorded in a room to multiple scenes. Click on a scene in the thumbnail display to paste development parameters.
In order to leave this mode, click on the img/ico_paracopy.jpg icon again.

The special room, "Latest," located at the bottom always stores the latest edited development parameters. Use this when you want to paste the latest results from adjusted development parameters to other scenes.

There are several convenient ways to use the "Cloakroom." Please see "6.4. Using cloakroom functions" for details.



4.1.3. Control box

Multiple sub-controls can be located in a control box.
Sub-controls for parameter categories in the main control are located at the top of the control box as tab pages.
A control box is added is "Arrange control box" is selected from the menu on the title bar through sub-controls in floating windows.
When an added sub-control is selected from an icon or menu under Parameter controls, the control box is scrolled and the selected sub-control is displayed.


4.2. Sub-control


Sub-control is prepared for each parameter category, and they are classified as the following types;

[List of sub-controls]

By default, it is displayed as selections on the tab page.
The taste dropdown list is located in the main control section.
(B) This sub-control is for adjusting parameters belonging to parameter categories for minute adjustments found in development parameters.
By default, it is set as a hidden floating window.
Displays can be switched either with [Display (V)] in the menu or with the sub-control icon located at the bottom of parameter controls.
(C) This sub-control runs and displays operation modes in the preview display.
It is displayed only when switching to the concerned operation mode.
(D) This sub-control is for displaying information. It is not a control for operating parameters.
By default, it is set as a hidden floating window.
Displays can be switched either with [Display (V)] in the menu or with the sub-control icon located at the bottom of parameter controls.
(E) This sub-control is for performing operation on tastes and development parameters.
By default, it is displayed as selections on the tab page.



*1 "Sharpness" and "Noise reduction" are divided into two sub-controls, but they share a common parameter category. Tastes are shared.
*2 "Development settings" do not have tastes.


4.3. Exposure Bias


You can determine exposure bias using a development gain when developing. This results in very similar exposure bias on a camera with processes equivalent to the push-process and pull-process on film.
You can perform adjustments by selecting an a value from the exposure bias slider.



You can take a photograph on the premise that you can adjust exposure bias at development process later. Please refer to '10.1.2 Utilizing Difference between Exposure Biases of Camera and SILKYPIX® Developer Studio Pro 5' for more details.

4.3.1. Auto Exposure Bias



Exposure bias can be performed automatically by clicking the Automatic exposure bias button.

The algorithm for automatic exposure bias in SILKYPIX® detects an object and analyzes its colors in detail. While restricting brightness and washed-out colors, it performs strong that employs the best of our image processing technology in order to utilize the ability to reproduce colors on your monitor or printer.


This is a quick way to getting the perfect exposure for your images, even if you underexpose your pictures a little. Slight underexposure is typical for RAW photography, as it prevents the highlight areas from loosing structure.
This feature helps reduce time when adjusting development parameters.

4.3.2. Fine-Tuning Exposure Bias



You can fine-tune your exposure with the spin-button that shows the highest and lowest values for exposure. This allows for more detailed adjustments to your exposure that cannot be done on the exposure bias slider.

We recommend that you make rough adjustments to exposure bias and then fine-tune it with the fine-tuning exposure bias.

Also, you can make revisions to automatic exposure values if you select "Auto (SILKYPIX evaluation)" as your exposure because this paramater can be selected independent from "Exposure." For example, you can make the automatic bias brighter if you set this to "Automatic exposure +0.5EV." Your image will be like performing exposure bias on the automatic exposure mode on your camera.



4.3.3. Exposure Bias Tool

Exposure bias tool allows you to adjust the brightness of a specified point to a certain exposure level.
Click the "exposure bias tool" button on the "Exposure" sub-control or on the toolbar./img/ico_whitepoint.jpg, then the operation mode is changed to the "exposure bias tool" mode.

When you click a point or drag a rectangular selection on the preview image using the "exposure bias tool", this feature sets an "exposure bias" in a way that brightness of the point or rectangular area selected becomes the "defined level".
The "defined level" is specified as the photosensitive level on the RAW data. You can change it in the "Function setting" dialog. Please refer to '9.3.1.2 Setting up Exposure Bias Tool' for more details.

This function works effectively even when a specified point is not a chromatic color. In that case, the largest value of R, G, or B is selected as a target value and the exposure is set to the "defined level". For example, when you click the red area, this feature sets an "exposure bias" such that the R value becomes the "defined level".

* About eyedropper operation, please refer to '9.3.2.2 Enable Continuous Operation of Eyedropper Tool'.


4.3.4. HDR / Dodging Adjustments

You can adjust HDR and dodging. Select HDR and dodging adjustments from dropdown lists. You cannot use them simultaneously.

4.3.4.1. HDR

HDR is short for High Dynamic Range imaging. It is a technique for photographic imagery that comes close to human memory.
Photographs cannot simultaneously image bright parts and dark parts. If you adjust exposure to the bright parts, the darker parts will break down, and if you adjust exposure to the dark parts, the brighter parts will break down. However, the human eye continually processes the luminosity and recognizes it as an image. Therefore, even when, for example, you look at a scene with great differences in brightness, you recall the image without breaking down the whites or darks.
Put simply, HDR is a photographic technique for imaging in a much wider dynamic range compared to normal photographic techniques.

Many conventional HDR techniques use a method of combining multiple images of different exposure to create a single image. This software employs HDR imaging from the data of a single image by utilizing the wealth of information found in the image data to the maximum.

Please search for the most effective adjustments as you adjust HDR to perfection.

4.3.4.2. Dodging Adjustments

Dodging is a technique for reducing exposure to photographic paper and adjusting partial brightness by covering dark parts in a printing process for wet photographs.

If the subject shows large differences in brightness, performing exposure bias to correspond with the darker portions will make the brighter areas too bright.
In such a case, you can finish your photograph with a greater gradation by appropriately adjusting the amount of exposure bias for each area of the image.

The dodging adjustments included in this software analyzes images and automatically distinguish between parts that do not have enough exposure and those that do, and then performs an exposure bias on those parts with a precision close to that of the human eye.

It reduces the exposure in areas that are too bright and adds exposure to dark areas, by adjusting each area to achieve a balanced brightness.
It is effective on images of subjects that have a great differences in brightness that come from areas of overexposed and underexposed conditions, where the dynamic range can be reduced to make bright portions and dark portions easy to view lower overall contrast differential.
You can adjust the amount of dodging to suit, so try experimenting to see its effect.




4.4. White Balance


White balance is the function to adjust white color.
Human eyes adjust to ambient light color. We perceive the white color of an object as the same under sunlight, tungsten lamps, and fluorescent lamps. However, digial cameras, "white" under sunlight can be recorded as white, while white under tungsten lamps are recorded as a reddish white, similarly fluorescent lamps are recorded as greenish or bluish white. What provides compensation for these color shifts is "white balance".

White balance adjustments vastly change colors in photos. A white object in the photo can be expressed most accurately and naturally with this function. In other words, the basic concept of white balance is the method of expressing white as white, irrelevant of color tint.

However, it is not always true for all types of scenes.
For example, if a white object in evening glow is expressed as a clean white, you will not be able to perceive this as sunset scene. If you want to produce a melancholy mood on your picture in a cloudy sky, it may be appropriate to add a blueish tint.

Although most cameras today can automatically adjust the white balance, it is not always accurate and even if it is correct, the result is not always what you intend. Therefore, it becomes necessary to adjust the white balance according to your artistic expression. However, it is very difficult to select and correct the white balance when taking a picture.

When taking a photograph in RAW, you do not have to consider a white balance setting since it is deemed a parameters only required in the process of developing RAW data into JPEG and TIFF images. White balance settings in digital cameras are required for development processing in the camera and for converting to JPEG / TIFF images. It is not absolutely necessary to save them to RAW data.
The set white balance is reflected in preparing preview displays for displaying in thumbnail images and liquid crystal displays on the back of the camera. Therefore, it is desirable to set a value as appropriate as possible, but you can freely change the white balance while processing developments later.

If you take a picture with RAW data, you can change the white balance to what you want when you are developing the photo for a particular expression of a scene. One of the major advantages of using the RAW data is this function.

4.4.1. Adjusting White Balance with Taste

This is the way to make adjustment by selecting the white balance adjusted for each light source in advance. Select a taste that specifies a light source in the dropdown list of "white balance".
You can also change settings in detail later, so it is convenient to select the light source first.
The preset items displayed in the dropdown list may be different for each type of camera.
There are "taste" that are prepared in the dropdown list of "white balance", which specify each light source.



Auto (Absolute) ...This automatically determines a suitable white balance. It automatically makes adjustments to cancel out color from the light source and color cast.
Auto (Natural) ...This automatically sets an appropriate white balance. It automatically adjusts in order to perceptually reproduce the atmosphere of the light source color. It is effective for retaining the color tone of the light source without completely correcting color cast from the light source color.
Daylight ...White balance suitable for shooting outdoors
 (Sunset)...White balance suitable for shooting in the direct sunlight of the evening glow
 (Fine) ...White balance suitable for shooting in the direct sunlight of daytime in fine weather
 (Daylight) ...White balance suitable for shooting in the direct sunlight in fine daytime (including obscured sky)
 (Cloud) ...White balance suitable for shooting in scattered light from clouds in overcast day
 (Shade)...White balance suitable for shooting objects in the shade in fine daytime (including obscured sky)
 (Fine shade)...White balance suitable for shooting objects in the shade in clean and sunny daytime
Fluorescent ...White balance suitable for shooting objects under fluorescent light
Three-band fluorescent ...White balance suitable shooting objects under three-band fluorescent light widely used in home
Tungsten ...White balance suitable for shooting objects under incandescent lamp
Flash ...White balance suitable for shooting objects in the photoflash

4.4.2. Auto White Balance

If "Auto (Absolute)" / "Auto (Natural)" is set in white balance, it will analyze the image and automatically adjust to a suitable white balance.
Don't worry. You can use the "auto white balance" function, which expresses a light source color in white automatically.
The method and logic of "auto white balance" of SILKYPIX® is fundamentally different from "auto white balance" in cameras. And it allows very accurate detection of the white balance of high color saturation or an object having no white area, which typical "auto white balance" function cannot handle well.

There is no correct white balance. Only "you," the one taking the picture, can make this determination based on what you want the photograph to express.
However, if many photographs are being developed, setting an appropriate white balance for each photograph would be a lot of work.
You can utilize Auto White Balance as a step for efficiently determining the white balance in many photographs.

Expressing white things in white is the basis of white balance. Ultimately, when you adjust white balance for effective production, it would be best to start your work by first adjusting to an appropriate white balance so that white things are shown as white.
If you use Auto White Balance, most photographs will be automatically adjusted to an appropriate white balance, so if you are making adjustments to many photographs, first try using Auto White Balance to improve the efficiency of your work.



There are two types of auto white balance: "Auto (absolute)" and "Auto (Natural)."
"Auto (absolute)" automatically makes adjustments in order to eliminate color casting from the light source color as much as possible.
"Auto (natural)" automatically makes adjustments in order to perceptually reproduce the atmosphere of the light source color. It is effective for retaining the color tone of the light source without completely correcting color cast from the light source color.



4.4.3. Color Temperature and Color Deflection

This is the way to adjust the white balance by specifying the color temperature.
There is a "color temperature" adjustment slider on the "White balance" sub-control.

Move this slider to find the point where colors of the object are well balanced.
When the color of the object is reddish or yellowish, move the slider to decrease the color temperature.
When the color of the object is bluish, move the slider to increase the color temperature.

The "Color deflection" slider is used to remove color casts. Before using it, adjust the color temperature first.
When the color of the object appears greenish, move the slider to the + side.
When the color of the object appears magenta, move the slider to the - side.

* Refer to '10.4.1 Color Temperature and Color Deflection' for your information.

4.4.4. Gray Balance Tool

This is a tool for adjusting white balance, targeting the gray subjects that appear in the photograph.

When clicking the "Gray balance tool" on the "White balance" sub-control or toolbar./img/ico_graypoint.jpg, you can enter the "gray balance tool" mode.

Then, click or drag the area that you want to change gray to specify the range. The white balance will be set to express that area in gray.

When there is a gray object in a photo, you can easily adjust the white balance with this function.
Taking a photograph of a gray chart or white paper in advance may be very helpful.

* For eyedropper operation, refer to '9.3.2 Enable Continuous Operation of Eyedropper Tool'.

4.4.5. Skin Color Tool

This is a tool for adjusting the skin of a person appearing in the photograph to an "expected pretty skin color."

You can switch operation mode to "Skin color tool" with the "skin color tool" button on the "white balance" sub-control, or menu command [Operation(M)]-[Skin color tool].
In the "skin color tool" mode, you can click or drag a rectangle area at the target skin on the preview, then the target area is automatically adjusted to beautiful skin color and also exposure bias is adjusted.
This tool is used at the same time as adjusting white balance and exposure bias.

There are times when adjusting skin color does not change as expected with one operation. If the result is too red, green, or blue, please click that area again. By a few repeatable operations, you can find out the suitable skin color.
Then you can additionally adjust "White balance adjustment", "Exp. bias fine tune", or "Tone" for fine-tuning.
If you use this tool on the woman's face, please avoid the emphasized make-up area. Basic foundation area, especially dull color area is suitable for picking up,

* For continuous operation, please refer to '9.3.2.2 Enable Continuous Operation of Eyedropper Tool'.

4.4.6. Dark Adjustment

While "color temperature" and "color deflection" change the white balance of the entire image, the "dark adjustment" amends color casts of the dark portion of the image.
Green or magenta color casts sometimes occurs in the dark portion although the white balance of the bright portion in a scene is well.
In this case, you can amend color casts with this function, and you can continuously remove color fluctuation from the dark portion to the bright portion.



For example, the left picture is an illustration of strong magenta casts in the dark portion.
Looking at the enlarged portions, you can see that darker portions have magenta in them. You can alleviate this phenomenon through using white balance only in the darker areas by adjusting them. The picture on the right is a sample of a photograph with the magenta casting removed from the darker areas using the dark adjustment function.


No corrections.

Dark Adjustment (Set value: -31)


Dark adjustment has been improved in SILKYPIX® Developer Studio Pro 5, and is operated differently from earlier versions. Please see "4.17.2 Compatible Mode" for details.

(1) Detail of color casts in the dark area

The main purpose of the function is to remove color casts in the dark area, however, with this function, you can also change the white balance of the dark area and bright area.

The left picture shows the photograph as shot. The picture in the center shows when white balance is set to "Fine," adjusting to meet the parts lit by sunlight in the back. However, the sunshine filtering through the foliage changes the color of the clothes greenish. If you use white balance on the color of the clothes, those colors will turn to magenta. In other words, you cannot achieve a balance between both the clothes and the sunlit portions using only white balance. Of course, since the sunlight is actually filtering through the foliage, the clothes look greenish and the center photograph reproduces the proper colors. However, as humans adapt colors, we feel the image is different from when the photograph was shot. In this type of case, you can adjust the white balance on the darker areas with dark adjustment. The photograph on the right is an example of removing the greens without changing by much the brighter areas lit by the sun with dark adjustment. This is quite close to the image at the time the photograph was shot.

(2) Using with "color temperature" and "color deflection"

When adjusting the white balance, first determine the white balance of brighter parts with color temperature and color deflection. Next, perform dark adjustment if you want to remove color casting in darker areas.

(3) Detail of color casts in the dark area

Why do color casts occur in the dark portion?
This is caused by current leakage of an image sensor. Because of the leakage current, the intense black is not recorded as zero value in RAW data. SILKYPIX® Developer Studio Pro 5 is subtracting such leakage current data from RAW data (optical black correction) to develop an image.
However, a higher temperature increases leakage current of an image sensor, and vice versa. In most cases, a camera records black with constant level, regardless of the temperature, but some conditions or photographing environment may affect the level (optical black level). According to the color sensitivity of each image sensor, as the optical black level becomes larger, the color of the dark area becomes magentish, and as the level becomes smaller, the color becomes greenish. The "dark adjustment" function reduces coloring of the dark portion in those cases. It also corrects the white balance of the dark portion when a photograph is taken under severe conditions such as extremely low temperature, high-sensitive photography, and long exposure.
You can make corrections without affecting brighter areas (except when parameters are in compatible mode) because dark adjustment is reflected after exposure bias from SILKYPIX® Developer Studio Pro 5.



4.4.7. Mixed light bias

This function automatically distinguishes and adjusts white balance when there are two or more different light source colors within the same image.

Mixed light refers to pictures where there are two or more different light source colors within the same image. For example, you may have a flash photograph while outdoors in the sunlight, causing a mixture of sunlight and the flash, or you may be indoors with light coming from a window, causing a mixture of outdoor and indoor lighting.
"Mixed light bias" alleviates part of the light source colors that are unnatural by adjusting the color temperature and color deviation.

You can adjust bias as necessary.



4.4.8. White Balance Adjustment

The menu command [View(V)]-[White balance adjustment] displays the "White balance adjustment" sub-control.
Use this function when you want to adjust the white balance at the final stage of your workflow e.g. tinting
You can adjust white balance in detail with this sub-control, which has a "white balance target" graphic control, a "saturation" slider, and a "hue" slider.


(1) White balance target
This graphic control is based on the accurate colorspace. You can set the white balance visually by clicking a mouse directly.

[Mouse wheel operation]

You can change "saturation" parameter with the mouse wheel on the white balance target.
And with [SHIFT] key, you can change "hue" parameter.

(2) "Hue" slider
It shows the angle from the right hand side of the white balance target in clockwise. Move the slider to change the angle in detail.
You can specify the setting value indicates:
0right from the center
90downward from the center
180
(-180)
left from the center
-90upward from the center
+lower half from the center
-upper half from the center


(3) "Saturation" slider
It shows the radius from the center of the white balance target. Move the slider to change the radius in detail. The range is 0.00 to 1.00 (0.00 is the center of the white balance target, 1.00 is the maximum radius).

4.4.9. Summary of Color and Adjustment

We will now introduce you some setting samples to show how to get the colors you want.

1) To remove reddish color (red casts)
(a) Move the "Color temperature" slider to the smaller (lower) side.


(b) With the white balance target in the "White balance adjustment" sub-control, move the cursor to the opposite (blue) direction.


2) To remove bluish color (blue casts)
(a) Move the "Color temperature" slider to the larger (higher) side.


(b) With the white balance target in the "White balance adjustment" sub-control, move the cursor to the opposite (red) direction.


3) To remove purplish color (magenta casts)
(a) Move the "Color deflection" slider to the - side.


(b) With the white balance target in the "White balance adjustment" sub-control, move the cursor to the opposite (green) direction.


4) To remove greenish color
(a) Move the "Color deflection" slider to the + side.


(b) With the white balance target in the "White balance adjustment" sub-control, move the cursor to the opposite (purple) direction.



4.5. Tone Adjustment


Tone adjustment parameter adjusts the contrast, high or low.


Use the "Tone curve" for making minute adjustments after you finish adjusting other biases.



4.5.1. Adjusting Tone with Taste

Select a taste from the dropdown list of "Tone".
Tones in incremental steps from Low to Strongest are included as maker tastes.



"Average" is the SILKYPIX default setting. "Average" is a higher contrast than that obtained using sRGB and Adobe RGB standard tone curves, and is set to improve the overall appearance of an image.



Setting to "Standard" will give similar contrast levels to sRGB and Adobe RGB standard tone curves.

4.5.2. Fine-Tuning Tone

Tone adjustment can also be made to "Contrast", "Contrast center, and "Gamma."



(1) Contrast
Contrast means the difference between bright area and dark area.
When increasing the contrast, the bright area becomes brighter and the dark area becomes darker, i.e. high contrast.
On the contrary, when decreasing the contrast, difference between the bright area and dark area becomes smaller, i.e. low contrast.

(2) Contrast center
This is the reference to judge the brightness when adjusting the contrast. Upper levers from the contrast center are considered bright, and lower levels are considered dark. In other words, this reference decides the point where the brightness level is not changed when adjusting the contrast.
When setting the contrast center smaller, the tone of an image becomes lighter.
This is because the contrast is increased based on the dark area, and causes the dark area to become smaller and the bright area larger.

For example, by strengthening the contrast, "Bright areas" become brighter and "Dark areas" become darker, but "Mid contrast" is the midpoint between "Bright areas" and "Dark areas," and there will be no influence on contrast.

When setting the contrast center larger, the tone of the image becomes darker.
While, setting the contrast center smaller, the tone of the image becomes brighter with the mid contrast level expanding.

Therefore, if a target object is dark, set the contrast center smaller, and if it is bright, set the contrast center larger to obtain an ideal tone.

[Utilizing Histogram]

Mid contrast is displayed with the img/ico_histogram01.jpg mark at the bottom of the histogram. The brightness of R, G, B where the mouse cursor is pointed to on the preview display is also displayed here.
When you use this function to adjust while looking at brightness distribution on parts you want to use contrast, you can find the optimal value relatively easily.

(3) Gamma
Gamma is a brightness adjustment. As the gamma increases, the overall brightness becomes higher, and vice versa.

You may think it is the same as exposure bias operation, however, they are not the same thing.

With the exposure bias, the brightness is adjusted without changing the ratio of bright range and dark range . However, with gamma, the ratio is changed.
When increasing the gamma value, the bright range is compressed, and the dark range is expanded.
When decreasing the gamma value, the dark range is compressed and the bright range is expanded.
Therefore, in this software, this operation is considered as a tone-change-operation and classified as 'Tone Adjustment' since it changes tone.

(4) Black level
Black level controls create clarity of the dark areas.
You can specify the level of black with this function. When increasing this parameter, the color black becomes deeper black.
This function works effectively when a picture is taken against the sun and the image becomes unimpressive, or when a landscape image becomes washed out, or when a landscape image becomes obscured or influenced by haze.

(5) Display graph in tone curve
By placing a check next to "Display graph in tone curve," you can display the status of adjustments here in a graph in the "Tone curve" sub-control.

By adjusting the "Tone" parameter when displayed as a graph in the tone curve, you can visually confirm the parameter status in the graph.
Displaying the "Tone" graph can also be useful when making further minute adjustments on the "Tone curve."



4.5.2.1. Black level tool

This tool designates and sets the black level on designated points or areas.
Enter Black level tool mode through either [Compatible mode (M)] - [Black level tool] from the menu or with the ./img/ico_blacklevel.jpg icon on the tool bar.

Click and/or drag on the area you wish to designate on the preview screen and adjust the black level to the level of brightness you desire.
The brightness level used here is the level of exposure in the RAW data. You can set the brightness level at "Function settings." Please see "9.3.1.3. Setting black level tool" for details.




4.5.3. Tone Curve



The "Tone curve" is a tool for making minute adjustments to tone expression after completing adjustments to other biases and for converting brightness for effect.



The menu command [View(V)]-[Tone curve(T)] displays the "Tone curve" sub-control. You can also display it using the sub-control icon "Tone curve" button.



Bias from the "Tone curve" is reflected after other bias processing is performed and converted to the color space on the output color space of development settings.
Therefore, for example, if you set monochrome to color, when you adjust R, G and B separately on the tone curve, this will not be monochrome, or if you change the output color space in the development settings, you will have to make readjustments to match the color space. Keep this point in mind when you use this.








You can set the curve (= Tone curve) that converts brightness on this sub-control. The horizontal axis means input (brightness of source picture) and the vertical axis means output (brightness results of a picture after adjustment). You can control lightness in a picture by operating this curve.

* By dragging window's frame of the "Tone curve" sub-control, you can adjust a size of the dialog. In addition, by dragging it while pressing the Shift key, you can adjust the size while fixing the aspect ratio of it.


4.5.3.1. Selecting a Taste

Several tastes that have good effects are included as Maker Tastes in tastes.

There are also special items such as "Initialization" and "Initialize All" within the tastes of the tone curve.
"Initialization" initializes only the tone curve of the selected channel (all RGB, R, G or B), while "Initialize All" initializes all four tone curves.

4.5.3.2. Editing Points

The curve is drawn as passing through a point, and you can operate the curve by moving the point.
Selected point information is displayed on the "Input / Output" control. You can move the point by editing the value in this control or by dragging the point on the tone curve.

(1) Adding Point
Click the mouse on a graph to place a point at the position.
You can also click img/ico_tonecurve01.jpg to switch to a mode that will add a point to the tone curve and add a point from the preview display.

(2) Selecting a point
Select a point for operations. The selected point is displayed with img/ico_tonecurve02.jpg.
You can switch selections by clicking the point with the mouse.

(3) Moving Point
Move the point by dragging the selected point on the graph or by changing the coordinate value of the point displayed in the "Input / Output" control.

(4) Deleting Point
Move and right-click the mouse on the target point to delete.
In addition, you can delete the current point by pressing the

4.5.3.3. Control explanation

[How to use "Add point" function]

Click "Add point" button to add the target tone point on the tone curve.

(1) Select the target scene on the preview window.
(2) Display the "Tone curve" sub-control and click on the "Add point" button.
Switch to a mode to add a point on the tone curve.
(3) Click the target point on the preview scene.
(4) Then the target point is added on the tone curve.
(5) Move the point and adjust the tone curve.
Moving the point edits the coordinate value by dragging the point on the tone curve or with the "Input / Output" control.
(6) Then the tone curve that you adjusted is applied to the target scene.


4.6. Color Adjustment


Color adjustment can be performed by selecting Color saturation adjustments, Color profiles or Color expressions.

Colors are improved under SILKYPIX® Developer Studio Pro 5, but operations differ from previous versions. Please see "4.17.2. Compatible mode" for details.



4.6.1. Adjusting Saturation with Taste

Select a taste from the dropdown list of "Color".




4.6.2. Fine-Tuning Saturation

The taste includes a range of saturation that is considered to be appropriate to normal use. However, if you want more or less saturation, or adjust saturation more precisely, you can set it manually.



4.6.3. Color profile

Color profile refers to the characteristics of color expressions. Select this from the "Profile" dropdown list in the "Color" sub-control.

Color profiles include "V4 compatible," "Natural," "Faithful," "Monochrome" and "JPEG/TIFF."

(1) V4 compatible
"V4 compatible" is a profile transferring colors that were used in parameter information from earlier versions. Use this if you want to maintain color terms from adjustments in earlier versions.

(2) Natural
"Natural" is a profile that creates colors standard to SILKYPIX.

(3) Faithful
"Faithful" features color expressions with plain harmonies. Even if you change the contrast with tones, color taste will be maintained. Therefore, you will be able to raise contract without over saturation and lower contrast without colors fading.

(4) Monochrome
"Monochrome" is used when making a monochrome photograph. You can choose from two different kinds of color expressions under "Color expression."

(5) JPEG/TIFF
"JPEG/TIFF" is a profile when image data is either JPEG or TIFF.

4.6.4. Color expressions

Color expressions determine the direction of color reproduction. You can select it from the "Color expression" drop list in the "Color" sub-control. The following are categories of color expressions: "Standard color," "Memory color," "Portrait color," "Film color" and "Monochrome."



4.6.4.1. Standard Color

This is the standard color creation of SILKYPIX®, which aims for true color reproduction.
This mode provides reasonably natural colors for many scenes.

4.6.4.2. Memory Color

True colors in photo are not always "beautiful colors."
It is common knowledge that colors in our memory, or colors of an object that we perceive are different from actual colors. Although they differ in individuals, we can see a trend and directional characteristc.
We consider the picture "beautiful" when colors in our memory or colors we perceive are printed in the photo.
This mode creates colors of perception.
Although the directional character is different for each color, in short, saturation tends to be higher than the "Standard color" mode.
This mode provides "beautiful colors" for many scenes, but colors of some objects with high saturation such as flowers become too vivid and over saturated.
In such case, adjust with '4.10 Fine Color Controller', set lower saturation level or lower development gain to correct the conflicting color.

Memory color 1 performs the same color reproduction as "memory color 1" in the previous version of the software. Memory color 2 provides a humanistic touch of memory color with a new color reproduction technology called "3-dimentional color mapping method."
Select the mode, as you like.

* When decreasing the development gain to express dark images, it becomes easier to reproduce the color of object with high saturation. This is because most display screens and printers are not good at outputting high saturation and brightness simultaneously.


This mode is not effective in portrait photography.
Skin tones, or oranges, are often over saturated. This allows for high expressions in this mode, but as for skin tones, there are many cases in which neither the subjects nor the photographer like this over saturation.
If you want more beautiful skin colors, select the "Portrait color" expression.


4.6.4.3. Portrait Color

With pictures of people, you can create "pleasing skin tones" by creating more natutal skin colors at the expense of accurate and neutral color reproduction.
Portrait color mode is a color reproduction which emphasises skin tones and is better suited to photographing people.

Skin color is easily effected by different lighting soures. More specifically, luminosity, saturation and hue of skin are all effected under different the light source.
In this mode, overall saturation is reduced with luminousity being given to skin tones. Colors which are distant from skin tones are slightly effected because of the necessity to achieve greater skin tone balance.

In "Standard color" mode, when you require "pleasing and expected colors" by adjusting the white balance, the color balance in parts other than skin may easily be effected or break up. However, in this mode, colors close to skin tones are reproduced as accuarelyy much as possible and are adjusted to obtain a normal white balance. Therefore, when used on portraits, both a natural background and pleasing skin tones are easy to achieve.

Female skin tones were mainly use as a reference in the development of this mode.
This emphasis in "expected" colors are especially strong in women, while men portraits seem to render better with tanned healthy colors (tinted slightly with yellow).

Therefore, the portrait mode may not be appropriate for male portraits if one wishes to use this for natural skin tones or brownish skin tones.
When this mode is not appropriate for your picture, use the "Standard color."

Portrait color 1 reproduces colors similar to "Portrait colors" in earlier versions of this software.
Portrait color 2 is a mode that provides skin color with a new color reproduction technology "3-dimentional color mapping method", which is different from Portrait color 1.
Portrait color 3 provides colors of clothes and background slightly shifted to "memory color" based on "Portrait color 2."


* In order to reproduce pleasing skin colors, appropriate white balance adjustments may be required.
In cases other than photographs under fixed light sources, adjusting these will inevitably involve some trouble.
Use these color modes according to your preference.

4.6.4.4. Film Color

This mode provides color reproduction similar to reversal film.


In film, the light source or exposure impacts on colors, this is different in digital cameras. If you want a neutral color when using film, the color of the light source is critical and the exposure range is limited.
Since we did not wish for this digital cameras to be limited in this way, we have adjusted each parameter to realize all adjustment functions including the white balance or exposure bias and film tone colors simultaneously.
Therefore, you can easily obtain film-like colors by simply selecting this film color expression.


However, the tone of the gray axis is not effected when changing this mode. Adjust the tone, too, if required.
Since the film tone mode (for example, vivid film tone V) makes saturation high, colors in that mode are effected according to the white balance adjustment.
In the "White balance" sub-control, adjust the white balance to create your favorite colors if needed.

4.10 Fine Color Controller' allows more precise color adjustment.



4.6.4.5. Monochrome

This is the color expression if "Monochrome" is selected as the profile.
Monochrome is performed in the same method as previous versions (Version 1.0).
Monochrome 2 produces natural monochrome photographs that approach the sensitivity of the human eye.
Select a mode that comes close to your own expression, based on the scene.
Making photographs monochrome is performed at the final stage of producing colors.
Therefore, you can make various types of monochrome by adjusting white balance and color expressions.



4.7. Sharpness/Noise Reduction


Sharpness and "Noise reduction" both have an own sub-control, but they belong to the common category of the development parameter.
Therefore they have a common taste dropdown list. Please remember that any taste generated from this function contains both sharpness and noise reduction parameters.
If you make sharpness stronger, then noise is also emphasized. Therefore you should try and balance the adjustment of sharpness and noise reduction at the same time, in order to achive better results.


Noise reduction has improved with SILKYPIX® Developer Studio Pro 5, and operations differ from earlier versions. Please see "4.17.2. Compatible mode" for details.



4.7.1. Adjusting Sharpness with Taste

Select a taste from the dropdown list of "Sharpness/Noise reduction".

4.7.2. Sharpness Adjustment

The sharpness adjustment of the software controls the outline phenomenon or noise occurrence mentioned above.
The preset value provides you with well balanced parameters , but you can also set them manually to make more precise adjustments.
Set to an appropriate strength while referring to printed results.

When switching to "Sharpness" sub-control, three sliders appear. The details are explained below.
Please refer to '10.1.8 Creating Extremely Clear Image' to make complete adjustment for sharpness setting.

(1) Outline emphasis
Use it to fix the overall level of the sharpness.

(2) Detail emphasis
Use it to fix the emphasis level of fine edge (detail).
When increasing this parameter, you can improve resolution of the detail without emphasizing outline.
However, this function emphasizes noise at the same time, remember to balance with noise level.

* Detail emphasis level changes according to both of (1) outline emphasis parameters and this parameter. When decreasing (1) outline emphasis, detail emphasis also becomes smaller at the same time. At first, make rough adjustments by (1) outline emphasis parameter and then adjust accordingly with this parameter.

(3) False outline ctrl.
Use this to adjust the level to control false black or opposite coloring which appearing around the outline when the sharpness is increased.
However, when this parameter is increased, color separation doesn't work well (The color in the color boundary between different colors is lost and the area becomes white).
Keep this parameter and the color separation in balance.

(4) Type
There are two types of sharpness algorithm, "normal sharp" and "pure detail".
Normal sharp is ordinary algorism.
Pure detail is an ISL original algorithm for obtaing higher resolution looking images. It gives a stronger effect than with "normal sharp".

4.7.3. Noise Reduction Adjustment

Noise means the rough texture that occurs in high sensitive photography. We call it high frequency noise in the software.
At the high sensitive photography, red, green, or blue spots appear, too. We call them color noise in this software.
The function to remove such noise is the noise reduction.
In this software, the noise reduction function has independent parameters for every category.
The following sections are summaries of the function of noise reduction.

4.7.3.1. False Color Control

The false color control function changes the process level of false color reduction.
The software enables one to reduce both false colors occur in the fine structure area (high frequency area) and color noise.
When too much color noise at high sensitive photography or false colors in the fine structure area occurs, increase the reduction level.
However, there are some limitations in this function.
As the reduction level becomes stronger, the color separation level goes down, which makes colors in the color boundary blur. Also, there is a problem of "color spill," which is the phenomenon that occurs when the vivid color leaks around the picture.
Therefore, too strong reduction level may decrease the picture quality.


4.7.3.2. Fringe removal

Fringe removal adjusts the strength of processing to restrain fringe.
Fringe refers to the phenomenon of purple and green coloring that does not exist in reality on the edges of less bright (dark) portions adjacent to very bright portions.
This kind of coloring can be removed.



4.7.3.3. Neat noise

This reduces broader noise associated with high sensitive photographs and generates a clean image.
This function reduces two different types of noise.
One is banding noise that runs horizontally or vertically. If you notice banding noise, strengthen neat noise to adjust so that the banding noise will disappear.
The second are runs of color and brightness brought about by noise. If you notice runs of color or brightness, further strengthen neat noise and false-color controls.

* Neat noise simultaneously performs processing in accordance with strength to remove banding noise and processing to neaten runs of color and brightness.
Strengthening to remove banding noise varies only through neat noise parameters. Strengthening neatness of runs of color and brightness changes both neat noise parameters and false color control parameters. (It is determined by the product of these two parameters.)
Therefore, when adjusting neat noise, adjust false color control at the same time.
If you notice banding noise, first adjust so that it disappears using neat noise, then control runs with false color controls.
If it is running colors and brightness, not banding noise, that you notice, first strengthen false color controls and then adjust neat noise.
When adjusting parameters, it does not matter whether you first do neat noise or false color control, but it becomes easier to drive parameters by using the above orders.
* The "Geometric NR" function provided in other versions (SILKYPIX Developer Studio 2.0, 3.0 and SILKYPIX Marine Photography 3.0) was integrated into neat noise.Neat noise automatically processes "Geometric NR" if an image taken by a camera that requires "Geometric NR" processing is being processed.
* Neat noise operates as "Geometric NR" provided in other versions if development parameters are in interchangeable mode. Please see "4.17.2 Interchangeable Mode" concerning interchangeable mode.


4.7.3.4. Noise Reduction

Use the "Noise reduction" slider in the "Noise reduction" sub-control to reduce the high frequency noise. This function reduces the noise, with using RAW data.
Also, you can remove noise that often occurs when the sharpness is increased. Use the "Noise level" and the "Noise cancel" in the "Noise reduction" sub-control.

Refer to '10.1.8 Creating Extremely Clear Image' for the operation.

4.7.3.5. Noise Canceller

4.7.3.5.1. Noise Level

Fix the level of outline for outline emphasis with this parameter. The sharpness adjustment of this software only works toward the outlines above the setting of the noise level, and not effective for the outline or noise under that level.
Therefore, increasing this parameter may remove the noise, which is too noticeable.
However, as it becomes higher, the resolution especially in areas of detail becomes lower.
If you want to increase the resolution of details, lower the noise level.

4.7.3.5.2. Noise Cancel

Specify the level to cancel the noise which is under the noise level set with the noise level function.
* If too much rough texture is seen in a photo, we recommend you to make the level higher to modify.


4.8. Development


4.8.1. Demosaic Sharp Adjustment

The "Demosaic sharp" in the "Development" sub-control fixes the development quality.

Normally, set this value around "80."

Set it lower for a picture with full of noise. Please refer to '10.1.4 Relation between Demosaic Sharp and Picture Quality' for more information.
You can change it temporary in order to speed up preview display. Please refer to '10.1.1 Speeding-up of Refreshing Preview' for your reference.

4.8.2. Resolution Plus

Resolution Plus is a parameter than can be used only if RAF files taken in WIDE mode on FUJIFILM FinePix S3/S5 Pro are developed.
As for the Super CCD honeycomb SRII sensor installed in FinePix S3/S5 Pro, low sensitivity pixels (R pixels) are located between high sensitivity pixels (S pixels).
At our company, we believed that we could raise the limited resolution by using information in low sensitivity pixels. This software has a development engine that makes constructive use of low sensitivity pixel information in resolution.
However, compared to high sensitivity pixels, low sensitivity pixels have only about 1/16 the sensitivity and there is a lot of noise, so when used in resolution, noise may increase and artefacts may be noticeable around the outlines.
This function, Resolution Plus, controls the extent of use of low sensitivity pixels in resolution.
When set to 0, low sensitivity pixel information is not used in resolution (even in this case, it is used as always in gradation reproduction and in high dynamic range processing).
When set to 100, the maximum is used in resolution.
This parameter is influenced by the Demosaic sharp settings. Adjust Demosaic sharp settings at the same time and balance jags in resolution and the outlines.

4.8.3. Colorspace
4.8.3.1. Input Colorspace

You can specifically set the input colorspace for a JPEG/TIFF image by this control.
SILKYPIX automatically determines the input colorspace of a JPEG/TIFF image according to the standard of EXIF2.21.
When the JPEG/TIFF image does not include the colorspace information or when the colorspace is recorded by other way that is not based on the standard of EXIF2.21, SILKYPIX treats the image as sRGB colorspace. Furthermore, if an ICC profile is attached, it will utilize the ICC profile's color space. (*1)
If an input color space cannot be detected and an input color space is not designated, it will be processed in sRGB.


When SILKYPIX® cannot determine the correct colorspace, it may not be possible achieve correct color reproduction. In this case, please set specifically the input colorspace by this control.



*1 SILKYPIX ® performs color management using the OS functions.
Please note that if an ICC profile incompatible with the OS color management system is attached, accurate color reproduction may not be possible.
Please refer to "Determining color space (input color space) for images for processing" for details.

4.8.3.2. Output Colorspace

Select colorspace in "Colorspace" dropdown list in "Color" sub-control to decide the tone expression at development, working colorspace adjusted by the tone curve, and colorspace for image file created after development.
You can select "sRGB" or "Adobe RGB."


sRGB is the standard colorspace for Windows. Since Windows handles sRGB colorspace by default, use the software with the sRGB setting generally.
Adobe RGB is effective in processing images which are intended for additional photo retouching software, or for printing purposes.
It has wider color reproduction range than sRGB, but cannot be utilised unless you have proper image processing environment to handle AdobeRGB color profiles (Note that an improper environment will generate strange colors).
When reading files output by Adobe RGB with other software, set Adobe RGB colorspace for the profile setting (Operation varies depending on each software, so refer to the manual of the software you are using).
This software also enables the embedding of a color profile indicating the colorspace into an output file. A file with an embedded profile allows transferring the colorspace to the software supporting the color profile.
In addition, this software complies with Exif 2.21 Specification and outputs Exif information indicating Adobe RGB colorspace.
Please refer to '9.1 Setting for Developed Image' for embedding profile or Exif information output.


* When selecting Adobe RGB, the preview is displayed based on Adobe RGB colorspace. Therefore, when the color management of monitor is not used, colors are displayed inaccurately.
When selecting Adobe RGB, set the color management of monitor to a valid profile so that the correct colors are displayed.
Please refer to '9.2.1 Color Management'.

4.8.4. JPEG/TIFF Processing Mode

You can switch enable/disable the function to process JPEG/TIFF image.


You can do this with the "For developing JPEG/TIFF images" button or placing a check mark in the "For developing JPEG/TIFF images" box under function settings.

You will not be able to edit JPEG / TIFF images with SILKYPIX if the check is removed (or the button is OFF) from "For developing JPEG/TIFF images."



In this mode, controls for making adjustments to development parameters are disabled and operations cannot be performed.
Utilize this in the following cases.

(1) When you do not want to make original JPEG / TIFF images subject to editing
If you are someone who always takes photographs in RAW, you can prevent mistakenly making image adjustments to JPEGs recorded at the same time as original images.

(2) When you view SILKYPIX development parameters recorded in JPEG / TIFF images
If you select a JPEG / TIFF image developed by SILKYPIX in this mode, you can view the development parameters included in the development results.
The development parameters displayed here are those set when developing the image.
You can copy these development parameters in the paste buffer or cloakroom and apply them to other JPEG / TIFF images.

Development parameters will not be displayed if the JPEG / TIFF images were saved under a setting that does not embed the development parameters or if the JPEG / TIFF image was recorded and saved by something other than SILKYPIX.

4.8.5. Reserved Development


Set reserved development for selected scene. When setting reserved development, you can develop a batch of multiple scenes from [Develop (D)] – [Batch Development (V) of Reserved Development Scene] in the menu.


4.8.6. One scene development

Develop one scene. Please see "5.1.1. Develop One Scene" for details.


4.9. Highlight Controller


Highlight controller function controls color creation in highlight area.
The menu command [View(V)]-[Highlight controller] displays the "Highlight controller" sub-control.
This function controls a color clip in the highlight area, where one of color components (R, G, or B) is saturated. There are several types of controls. The "Chroma/Luminance" and the "Saturation/Hue" controls impact on the area where at least one of color components is saturated. The "Restoration" control restores the lightness of the area that were clipped at capture. Combined with under exposure bias adjustment, you can restore gradation to areas that have clipped. You can restore gradation to areas that have been whiteout.


The Highlight controller has improved with SILKYPIX® Developer Studio Pro 5, and operations differ from earlier versions. Please see "4.17.2. Compatible mode" for details.





4.9.1. Emphasis on Chroma/Luminance

Chroma/Luminance controls the priority of chroma or luminance to create colors in the highlight area.

The following pictures were developed based on the RAW data with highlight area (flowers). They were developed with chroma, luminance, or intermediate between Saturation/Tone.
Chroma emphasizes the colors of the flowers, and "Luminance" controls the highlight area effectively to emphasise the glare of the reflected light.



Chroma (value: 0)



Intermediate (value: 25)



Luminance (value: 100)




Here is another sample.
Highlight controller works effectively with the lighter area such as the sunset scene.
The following pictures, which are sunset scenes, were developed with each priority, chroma, luminance, and intermediate between them.



Chroma (value: 0)



Intermediate (value: 25)



Luminance (value: 100)


4.9.2. Emphasis on Saturation/Hue

After giving priority to chroma with the "Chroma/Luminance" slider, you can also control the priority of saturation or hue to finish development process.

As shown below, since R value (red) of the orange flower in orange was saturated, the hue of the highlight area became yellowish.
In such case, emphasize the hue with the "Saturation/Hue" slider to prevent reversal of the hue.
This process is also effective for the highlight area of skin, which sometimes becomes yellow.



Saturation (value: 0)



Intermediate (value: 50)



Hue (value: 100)


In some cases, it is more helpful to give priority to saturation.
In the following picture (a bee and a flower), you can see the color of pink and yellow are nicely reproduced by putting priority on saturation.



Saturation (value:0)



Intermediate (value: 50)



Hue (value: 100)


4.9.3. Luminance Restoration

This function restores original colors, which were lost by over-exposure photography.

In RAW data, the color information may be recorded correctly even though it is lost on the photo.
In such case, make the exposure bias under at the capture stage and you can restore the tones recorded in RAW data.
However, the area where the sensor is saturated cannot be restored with this way. Restoration enables to restore the lost lightness information based on information provided with a sensor with lower sensitivity.

The left is a picture of RAW data, which was taken with exposure set to the trees and ground and developed without exposure bias. The center picture was developed with -2EV exposure bias. The tones of the sky and clouds were restored and you can check lens flare. The right picture was restored by restoration.
As you see, the sky and clouds become clearer with this operation.



Restoration(value: 0),
No Exposure Bias



Restoration(value: 0),
Exposure Bias(-2.0)



Restoration(value: 128),
Exposure Bias(-2.0)


In addition, the following example is created with the image combine of the upper left picture and the sky and clouds in the right picture.
This shows the best result with the restored sky and clouds, and appropriate exposure on the trees and ground. This sample takes full advantage of development based on RAW data.
When you create two types of developed pictures with different exposure bias and restoration parameters, and combine them with a photo-retouching software, you can operate with wide dynamic range and create a better photo. This is the excellent advantage of RAW data.


Composite Picture



The example mentioned above is an example that comprised two development results with different exposure bias from photo retouching software. However, there was no trouble in the composition by using dodging adjustments in this software. You can compress and expand dynamic range by using exposure bias on parts of a large photograph with greater differences in brightness.
Please see "4.3.4. Dodging adjustments" for details.


4.9.4. Dynamic Range

This function allows you to compress the highlight gradation.

If you set it larger value, you can make smooth gradation of highlight area or make detail expression of highlight area. Areas under moderate brightness will not be influenced.
This compresses and stores RAW data of a wider range in highlighted sections, so the effects are such that gradation of highlighted sections is smoothed and details in highlighted areas are emphasized. On the other hand, highlighted sections become more moderate.

Please remember that you cannot use this function for overexposed scenes.

If you adjust the "Dynamic range" alone, basically, it will be necessary to leave extra information in highlighted sections. Decide how much extra information to leave and how effectively it will function. If there is absolutely no room in the highlighted sections there will be no effects even if "Dynamic range" is adjusted.
If the highlighted section has more than 1.0EV space available and "Dynamic range" is set to 1.0EV, highlighted sections are compressed so that values of 1.0EV brightness are expressed as pure white more so than values expressed as pure white to that point.

4.9.4.1. Method for Effectively Utilizing Dynamic Range

In order to effectively utilize dynamic range, you must not lose highlighted parts during photography.
It is also desirable to have as much headroom as possible in the highlighted area when taking a photograph.

The method for taking photographs without losing highlighted portions and with as much headroom as possible depends on the functions of the digital camera that you use.
Generally, photography that does not lose highlighted portions is possible by taking underexposed photographs, but there are cases in which it is hard to lose highlighted portions even when taken with a reasonable exposure using your digital camera. Using a digital camera with a wide dynamic range is advantageous.
However, no matter how wide the dynamic range of the digital camera photographs is, it makes no difference if it loses the highlighted portion. Not losing the highlighted portion is the most important condition when taking pictures.
Develop an effective photography method taking into consideration the characteristics of the digital camera you use. How effective you are when taking an underexposed photograph differs depending on the type of camera you use, its mode, the surrounding environment and the purpose for creating the image. You must pay attention, because taking photographs that are too underexposed leads to increased noise.

As an example, the following explains shooting and developing with a digital single-lens reflex camera with RAW data recorded at 12-bit gradation.
This is a technique for giving attention to the expression of the highlighted parts, so generally, there are many times when the subject is bright enough and it is possible to photograph with an ISO film speed of minimum sensitivity. Under these type of photography conditions, take underexposed photos decisively at 1.0EV ~ 2.0EV when clipping is a concern for the subject. Keep the ISO film speed as is and take your photographs with your camera's exposure bias function set to -1.0EV ~ -2.0EV.
If you correct to a camera exposure bias of -1.0EV and take your photograph, the shutter speed doubles and exposure time is halved. If you develop this photograph as is, you will end up with a dark photograph under 1.0EV, so sensitize SILKYPIX's exposure parameter to +1.0EV.
Under these conditions, there are almost no changes if you take your photograph under normal exposure and develop it without sensitization. One disadvantage of sensitization is that it emphasizes noise, but you cannot tell most of the increase in noise if sensitization is around +1.0EV ~ +2.0EV with a digital single-lens reflex camera.
This condition means that brightness information will retain 1.0EV better than information projected on the image as development results. This makes it possible to utilize the space from the highlighted portions and express the highlights.
If photographed at under 1.0EV, the dynamic range parameter functions effectively at 0.0 ~ 1.0EV. If photographed at under 2.0EV, the range of adjustments will increase to 0.0 ~ 2.0EV.

* When using FUJIFILM FinePix S3/S5 Pro, gradation to somewhere over 2.0EV is recorded if you photograph in RAW at a setting of dynamic range mode = wide.
* Compared to conventional 12 bit devices, Nikon and Canon 14 bit devices record gradation to somewhere over 0.5EV ~ 1.0EV.
* When RAW photographs are taken with a Canon 14 bit device in a mode that gives priority to high brightness and gradation, gradation is recorded at somewhere over 1.0EV above conventional photography mode.
(*1) This depends on the S/N ratio (ratio of image signal to noise) of the photographed image. This assumes it was photographed at low sensitivity with a digital single-lens reflex camera. If using a small digital camera with an image sensor and taken at high sensitivity, sensitization may be severe.


4.10. Fine Color Control


The fine color controller is a powerful color adjusting function that can freely handle colors.
Select [Display (V)] – [Fine color controller] from the menu to display the "Fine color controller" sub-control.


It can also be displayed from the fine color controller icon in the sub-control icons at the bottom of parameter controls.




The fine color controller divides colors into 8 hues and provides a function for adjusting colors in each of the hues.
The color circle hue display shown on the control is arranged so that white is in center of the chroma chart, with color positions starting at the 3:00 position on a clock and going clockwise in the following order.


Color name
Rose red
Purple
Ultra marine blue
Turquoise
Blue-green
Green
Yellow-green
Golden yellow

Color placement is arranged on this color circle such that the further from the center of the color circle, the higher the chroma, and they are placed at average color intervals as much as possible to meet human perception.

* A chroma chart of average color differences, called the CIE 1976 UCS Chroma Diagram, is used on the color circle.


There are two main ways to adjust parameters on the fine color controller. These are a method of operating a mouse on the color circle and a method of setting parameter values using a slider control.
Please use these together for effective parameter adjustments.


The Fine color controller has improved with SILKYPIX® Developer Studio Pro 5, and operations differ from earlier versions. Please see "4.17.2. Compatible mode" for details.


4.10.1. Adjustments using the color circle

As seen in the diagram of the color circle shown above, the color circle is divided into 8 hue blocks, and there are operation points in each of these blocks.
(1) shows a block, and (2) shows an operation point.

A hue for operation is selected by clicking any of the 8 blocks. Borderlines of the blocks of hues for operation are displayed in bold.

Operation points in each block can be moved by dragging the mouse or with the mouse wheel.
With either of these methods, movements along the circumference are interlocked with "Hue," and distance from the center of the color circle is interlocked with "Chroma."
Adjusting the "Brightness" parameter can be done with the mouse wheel, but it will not be shown on the color circle.
Parameters adjusted through mouse operations are reflected on the slider control, so both the color circle display and the slider control display are synchronized.

[Mouse wheel operation]

You can operate the "saturation" slider with the mouse wheel on color circle GUI.
[SHIFT] key + mouse wheel is for the "hue" slider and [CTRL] key + mouse wheel is for the "lightness" slider.


4.10.2. [Adjusting with the sliders]

Adjustments to each parameter value on standard controls, compared to the method of adjusting the color circle with the mouse, will be explained here.

(1) Enable checkbox Enable the fine color control.
(2) Hue adjustment Select a hue for adjustment from the dropdown list.
(3) Hue Set how much change in hue. Set the angle in counter clockwise rotation from the reference point.
(4) Saturation Set the ratio assuming that the distance from the center of the color circle to the reference point is 100%.
When setting -20%, the operation point moves to the inside by 20%, and the saturation level is decreased. When setting 20%, the point moves to the outside by 20% and the saturation level is increased.
(5) Lightness Set the ratio assuming that the lightness of the reference point is 100%. When setting -20%, the lightness level is decreased, and setting 20%, it is increased.
(6) img/ico_fcc01.jpg (Initialize) Return all points to the initial state.


4.10.3. Methods and Notes on Utilizing Fine Color Controller

The Fine Color Controller is a color transformation tool that displays emphasized colors or, conversely, moderates them, and changes colors.
It is advantageous to perform adjustments on the image as the last process because color engineering is a type of image processing that destroys the balance of colors.


We hope that you will experiment and use the various functions, but one matter that requires attention is that it is advantageous to adjust white balance, exposure, color profiles and color expressions before adjusting the fine color controller.
White balance and exposure are basic adjustments and giving priority to these adjustments does not mean that you are limiting fine color controller, but if you perform fine color controller adjustments first, you may not be able to adjust the white balance and exposure as you would like.
The color profile and color expressions are items you should try adjusting before using the fine controller if you want to emphasize the subject.
It would not be an exaggeration to say that the color profile and color expression are types of fine color controller tastes. First select a color profile and color expression that seems to be desirable before independently adjusting the fine color control.


[Example of adjustment] One example would be a photograph of a person as the main subject taken close up against a background of a blue sky and red flowers.

(1) If the sky turns purple under the influence of white balance adjustments so that the person's skin color is a favorable pink, adjust so that the sky turns into a favorable sky-blue.
=> This technique is for adjusting only colors that seem strange such as when a sense of incongruity is born out of the entire photograph due to over emphasizing the main subject by not using the right amount of white balance.
(2) After appropriately adjusting the white balance, adjust the orange and red so that the person's skin color will be flattering, and then further adjust so that the blue sky will also be a good color.
=> This is a technique for true adjustments of basic correct white balance and adjusting so that the colors you want to emphasize are favored.
(3) Adjust so that the red flowers become pink.
=> There may be cases when you do not want to emphasize colors or adjust to a memory color, but rather make adjustments with the effect of changing colors to something different than reality.
(4) If red flowers are two bright and there is a whiteout effect, control the whiteout by lowering the red chroma.
=> Adjustments with the highlight controller to exposure and saturation will influence not just specific colors, but the entire photograph. This is an effective method for adjusting only specific colors.
Please see "10.1.5 Mitigating Whiteout" for details.


* If the mouse cursor is over the preview image, the color the mouse cursor is pointing to will be displayed in a circle over the color circle. Placing the mouse cursor where you want to adjust on the preview image will be an indicator of what color block would be good to adjust.
* This parameter category can be turned on / off. Please see "4.17.1 Turning On / Off" for details.


4.11. Lens Aberration Controller


Lens aberration correction is a function to correct lens aberration at development in order to create high quality image.
The menu command [View(V)]-[Lens aberration controller] displays the "lens aberration controller" sub-control. The sub-control can be displayed also with the lens aberration controller button./img/ico_lens.jpgunder the left.
Photo lenses have aberration. Today, the resolution of digital camera has improved, therefore, lens aberration may have a damaging effect on the picture quality. There are various kinds of lens aberration such as spherical aberration, coma aberration, astigmatism, curved field, distortion aberration, axial chromatic aberration, chromatic aberration of magnification, and shading reduction that is a decrease of light volume occurring in the periphery. To adjust these aberration three corrections are available:
shading, distortion, and chromatic aberration.



4.11.1. Shading (Peripheral Brightness Reduction) Correction

Shading correction is a function to correct light falloff at edges, which is a characteristic of a lens, making an area around the object darker. Use two parameters to correct shading.

4.11.1.1. Angle of View

Input the diagonal angle of view of the lens at photographing. Calculate and correct shading on lens design theory from this angle.

On a lens, light volume is decreasing toward the periphery area. The angle of view is larger in a wide-angle lens and smaller in a telescopic lens.
Based on conversion to 35mm film format (full size digital single-lens reflex camera), the angle of view of a 50mm standard lens is approximately 46 degrees, that of a 135mm telescopic lens is approximately 18 degrees, and that of a 35mm wide-angle lens is approximately 63 degrees. When you input the angle of view,shading correction of a lens is performed through the calculation of logical lens shading.

However, it does not always match to the actual shading of the photograph. (Please refer to '4.11.1.3 Detail of Shading Reduction') Please move the slider and find the best point using the value mentioned above.

4.11.1.2. Correction Ratio for Amount of Light

Input the ratio that you apply for the correction.
When you set the amount 0%, no correction is performed, and the amount 100%, the logical value calculated based on the angle is used. You can set the parameter up to 120%.

You can use this function to adjust the level of correction for the following cases. The case you want to remain the shading effect without complete correction since the shading is one of the tastes that are unique to a lens. Or a case that a bright object is on the periphery of a photo and when you make corrections it becomes too bright and lost.
You can also increase the shading level by setting minus value. Use the value to emphasize the center area on purpose by darkening the periphery, or to make the background quiet.

4.11.1.3. Detail of Shading Reduction

Reducing shading happens through several complex factors.

Although image formation is distorted in a wide angle lens, the lens periphery tends to be lighter as the object is much distorted.
For example, fish-eye lens prevents the shading effect by distorting the object in the lens periphery.
On the contrary, with a wide-angle lens, generally, corrections to distortions are performed so that a straight line appears as a straight line, but the perimeter of the image becomes dark because this method corrects by enlarging the perimeter.

Also, in a certain type of lens, a lens aperture seen from an oblique direction becomes smaller (vignetting), and such lens causes larger shading effect in the periphery area than the logical features.
An aperture value also impacts on the shading level. When it is the minimum value, large shading is caused, and when it is a larger value, shading becomes smaller.
Moreover, with a digital camera, oblique incidence to the image sensor causes shading.

Therefore, use the angle of view for reference only. Find the best-balanced point by yourself.
It is helpful to understand that correction amount becomes smaller and correction between the center and periphery becomes linear when making the angle parameter smaller, and correction amount becomes larger especially in the periphery when making the angle parameter bigger.
When you find that most of the area is corrected well, except the periphery area, make the parameter bigger to increase the light level in the periphery. When the relationship between the most of the area and the periphery is less, make the parameter smaller.

4.11.2. Distortion Correction

Distortion correction is a function to correct distortion aberration, making a straight line less distorted. Before using this function, check the "Distortion" checkbox.

4.11.2.1. Distortion Rate

See the right picture. When the image is distorted like a barrel, move the slider to the left to set minus value. Adjust the parameter with the slider to the point that the distorted line becomes straight. If the image is distorted like a pincushion, shown in the left picture, move the slider to the right to find the best point. If the slider stays at the center 0, no correction is performed. After the correction, you can compare the original image with the corrected image by checking and non-checking the "Distortion" checkbox.


Pincushion Shape

After Correction

Barrel Shape


4.11.2.2. Center/Edge Control

Determine which one should take priority when adjusting distortion, center or edge.
If the image around the center is distorted greatly even though the straight line at the corner is corrected well, move the slider to select the center priority. If the distorted level around the center is too weak, move the slider to an opposite side.
Iterative adjustments of this parameter and distortion rate can correct almost all of the distortion charateristics found in photo lenses. If you use this parameter properly, it is possible to correct or modify a lens having complicated distortion aberration.





Original



After Correction
(Rate: -16)


Most camera lens distortion can be driven to a point where it is not noticeable by alternately repeating these parameter adjustments and adjustments to the distortion rate. It is possible to correct or mitigate even from a lens with complicated distortion characteristics, such as the so-called jingasa (complex barrel) type, if these parameters are adjusted effectively.

4.11.2.3. Automatic Bias

Cameras have an automatic bias function for distortion. Cameras can be set this automatic bias for distortion ON or OFF, and if it can correspond with SILKYPIX® Developer Studio Pro 5, the automatic bias button will be displayed. This setting allows you to change automatic bias later.
If set to "Camera Setting" it will perform bias based on the value set on the camera when the photograph was taken.
If set to "Enable" automatic bias will be performed regardless of the value set on the camera when the photograph was taken.
If set to "Disable" automatic bias will not be performed regardless of the value set on the camera when the photograph was taken.
Automatic bias will be performed at the value already set, regardless of the status of checking "ON" for distortion bias on SILKYPIX® Developer Studio Pro 5.
Automatic bias and distortion bias on SILKYPIX® Developer Studio Pro 5 is performed seperately. If both are ON, both will be performed.


Automatic trimming of protruding areas and enlargements so that the original image size will be the same are performed through distortion correction. Protruding pixels can be taken out through distortion correction by using the "Expansion" function in the trimming function.
Please also refer to "4.13.4. Trimming expansion."

Distortion correction functions were developed with the aim to correct lens distortions, but it is possible to use them in various ways, such as alleviating the phenomenon of radial images from wide-angle lens through exaggerated perspective, or on the contrary, strong distortions. Different from the simple transformation functions in photo retouching software, corrections performed here simulate distortion characteristics that occur with a lens in reference to the design of an actual photographic lens.

The next example is of a transformation from strengthening distortion. The image before corrections (left side) shows a bubble and face that has been distorted, but the distortion is transformed to a natural form in appearance by making corrections that strongly twist the distortion (right side).

After corrections (Distortion rate: 50, Mid / surrounding stress: -50)


Enjoy combining various parameters that give you the feeling you have a lens that can freely control distortion. You will surely find new expressions.

4.11.3. Transverse Chromatic Aberration Correction

Transverse chromatic aberration correction is a function to correct false coloring on the edge around objects in an image. The transverse chromatic aberration is a disadvantage specific to an optical lens.

The transverse chromatic aberration is caused by the difference in lens magnification rates for each colored light (red light, green light, and blue light) incoming to a lens.

The transverse chromatic aberration correction is performed by changing R and B magnification slightly.

First, enlarge the area, where the edge of an object in the image periphery is colored, to more than 400%, and display it (Please refer to '[Reason to enlarge more than 400% and selecting edge for proper correction]').
Then, decrease the false color control in the "Noise reduction" sub-control (for example, 0 - 80).
After that, check the "Chromatic aberration" checkbox to adjust the R rate and the B rate.

When you correct a picture, enlarge the periphery area as shown below to check the correction result and change parameters.

4.11.3.1. R Rate

This adjusts the lens magnification for red light. If the edge is colored by red or cyan (complimentary color of red), change this parameter first.

4.11.3.2. B Rate

This adjusts the lens magnification for blue light. If the edge is colored by blue or yellow (complimentary color of blue), change this parameter first.

When these two parameters are appropriate, coloring is decreased most.
First, look the edge condition and change the R rate so that "red <--> cyan" in the both sides of edge is decreased. Then change the B rate to adjust "blue <--> yellow" coloring. Repeat the R rate and B rate adjustments to find the best point.

Do not try to decrease coloring, but try to distribute the edge coloring uniformly. After that, when increasing the "False color ctrl" slider in the "Noise reduction" sub-control, the remaining colors are disappeared. Increase the parameter until you are satisfied, and finish adjustments.

At this time, if colors still remain even after the false color control is maximized, there is a possibility that transverse chromatic aberration is so big that it exceeds the correctable range or that coloring occurs because of aberration other than transverse chromatic aberration. For example, too light background shows a possibility of coma aberration.
At the present time, you can correct transverse chromatic aberration.

4.11.3.3. Transverse Chromatic Aberration Tool

This tool allows you to adjust "R rate" and "B rate" by one action.
Click ./img/ico_ca.jpgbutton to switch operation mode to "Transverse chromatic aberration tool", and drag the target rectangle area on the preview image.
Then "chromatic aberration" parameter is automatically calculated.

Please retry a few times with another position until you get the good result.
* Please refer to [Reason to enlarge more than 400% and selecting edge for proper correction].

[Reason to enlarge more than 400% and selecting edge for proper correction]

Enlarging preview with more than 400% stops simplified development and glare at the time of updating preview, so you can view images more easily. In transverse chromatic aberration correction process, it is recommended to set the preview ratio with more than 400% in order to check changes in the image and to adjust parameters. If updating preview according to parameter changes is too slow to display, increase the preview ratio more, or make the window for displaying updated preview smaller.
It is preferable to select the edge you want to change when enlarging a display for adjustments. Please pay attention to the following points.

(1) Do not select edges in too light (white) background.
The background of the sample is not lost, though, the tone of this picture is light and aberration appears in the twig against the background of the light sky. You should not select the point in such background for aberration correction. The white background is too shiny, and coloring is generated by not only transverse chromatic aberration but also by other aberration such as coma aberration or astigmatism that make difficult to adjust parameters.
(2) Select an edge perpendicular to a radial line through the image center if possible.
Transverse chromatic aberration appears because of difference between the magnification for each color. Therefore, it hardly appears on the radial line through the screen center and often appears on the edge perpendicular to a radial line through the screen center. Selecting the edge perpendicular to the radial line makes parameter adjustments easier.
(3) Select an edge in the periphery of the the target image if possible.
Transverse chromatic aberration impacts most on the periphery of the screen. Coloring is becoming stronger in the area far from the center of the image. Check the edge in the image periphery to make adjustments.


* This parameter category has Enable/Disable setting. Please refer to '4.17.1 Enable/Disable for Parameter' section.



4.12. Rotation/Digital Shift


The menu command [View(V)]-[Rotation/Digital shift] displays the "Rotation/Digital shift" sub-control. The sub-control can be displayed also with the Rotation/Digital Shift button under the left.



* When you are changing "rotation/digital shift" parameter, grid is displayed automatically as default setting. (Please refer to '9.2.4.3 Grid Setting')






4.12.1. Rotation

Rotation is a function to rotate an image.
This software allows -45degree to +45degree rotation.

Then, by using the "expansion" in the trimming functions, the image is enlarged and trimmed so as to maintain the same pixels as the original image.

This software allows large rotations of -45degree to +45degree, but larger areas will be lost with larger rotations.
In this case, you can cut off necessary parts by using the trimming "Expansion" function and displaying all pixels lost through rotation.

4.12.1.1. Rotation Tool

Rotation tool can correct a slant horizontal/vertical line to a horizontal or vertical.
You can use this tool on "preview mode" or "combination mode". You can use the "rotation tool" by clicking menu command [Operation(M)]-[Rotation tool] or button on the "Rotation/Digital shift" sub-control.

Then the mouse cursor shows you "rotation tool" mode. In this mode, please trace the horizontal line or vertical line by mouse dragging.
Then the rotation angle is set automatically so as to correct the horizontal line or vertical line horizontally or vertically respectively.

4.12.2. Digital Shift

Digital shift has advantages such as shift lenses have.

With this function, you can make perspective control, or correct a distorted building to a straight one.



The "V perspective" slider can change the magnifications for the upper area and lower area of the image. When moving it to the left (smaller value), the magnifications for the upper area becomes larger, and to the right (large value), the magnifications for the lower area becomes larger. The "H perspective" slider can change magnifications for the left area and the right area of the image. When moving it to the left, the magnification for left area becomes and to the right, the magnification for the right area becomes larger.



The modified image shape becomes a trapezoid or distorted rectangle, however, it is automatically trimmed and modified to restore the original shape at the original aspect ratio. Therefore, the number of pixels does not change, avoiding resolution reduction due to deformation.

In this case, the "expansion" of the trimming function is used. Please refer to '4.13.4 Expansion of Trimming.'

Digital shift can be applied to a wide range of photographs, not just pictures of buildings. As seen in the following example, you can reduce the size of a face and make legs look longer in pictures of people. This is an example (after corrections) of an image (before corrections) where legs look longer by making the difference in distance look shorter with a digital shift of +6 (bottom: fall).



The Original

After Correction (V perspective: -80)


The deformation of this process is not a simple conversion from a rectangle to a trapezoid, but the projection conversion from three-dimensional space to two-dimensional space. This is the same type of conversion when taking a picture of real three-dimensional objects with a camera. Then you can get the same effect of using a shift lens.

Using this tool, you have the lens which can shift freely. Try various combinations of parameters to find a new expression.



4.12.2.1. [Angle]

You will need information on angle of view of a lens in order to get the right effect of digital shift.
The default angle-of-view parameter is set almost properly based on the EXIF information of the input file.
However, when you don't attach a manufacturer-made lens or attach an old lens, the angle of view may not be set properly.
If you find that the image is distorted vertically or horizontally after the digital shift process, adjust the "angle" parameter.

Frequent use of the "angle" parameter gives an impression as if the aspect ratio with digital shift changes.
Enjoy this as a part of the expressions.

* This parameter category can be turned on / off. Please see "4.17.1 Enable / disable settings" for details.


4.13. Trimming


Use when making a creation by trimming a part of the image in a photograph.

Trimming area settings can be performed by switching "Operation mode" in the preview display to "Set trimming area."
The "Operation mode" of the "Set trimming area" can be used only if the "Preview window" is displayed from either "Preview display mode" or "Combination display mode."

Switching to "Operation mode" can be performed by selecting [Operation mode (M)] – [Set trimming area] from the menu, or by clicking on the ./img/ico_trimming.jpg icon in the tool bar, or by pushing [CTRL] + [T].
When "Operation mode" changes to "Set trimming area," the "Set trimming area" sub-control will be displayed along with handles for controlling the frame lines that show the trimming area on the preview image.


When a trimming area is set, a trimming mark will be displayed on the thumbnail.

When setting trimming areas, first determine a format for setting the trimming area with "Area setting format."
You can freely set the trimming area into a rectangle, and can perform trimming in accordance with the purpose of the output by fixing the aspect ratio.

There are three way to set the trimming area: Adjusting the handles displayed in the "Preview display" with your mouse; Adjusting parameters in the "Set trimming area" sub-control; and designating with the "Trimming tools."

The trimming area has to be set for each scene, but the "Area setting format" is common to each scene as a software setting.

4.13.1. How to Operate Handle in Trimming Area

Trimming areas can be set by using the mouse to operate handles displayed on the preview image.

(1) Set the area with each handle at every corner and every side.
(2) Move the area with the center handle.
(3) The trimming area rotates 90 degrees when the rotation handle to the right of center is clicked.

* The trimming size is automatically adjusted so that the aspect ratio is always constant, except for when "Area setting format" is set to "Free size."


4.13.2. How to Operate "Setting for trimming" Dialog
(1) Trimming area in selected scenes Set a numerical value for the trimming area.

(A) Upper left coordinates (x,y)
(B) Size (width x height)
(C) One coordinates (x,y) for the area
(D) The other coordinates (x,y) for the area



(2) Specifying method Select a method for setting the trimming area.
Select from "Free size," "Aspect ratio of image," "Aspect ratio setting," "Print size" and "Fixed size."
Free size Designate when freely setting trimming size.
Aspect ratio of image Trim while maintaining the aspect ratio of the original image.
Designate when trimmed image and original image share the same aspect ratio.
Aspect ratio setting Designate when trimming to your own set aspect ratio.


(Set output size) When this setting is on, the numerical value of the aspect ratio set here is the default pixel size at the time of one scene development.
For example, if trimming is set here to 640:480, whatever value the size of the actual trimming, the default pixel size at the time of one scene development will be set to 640x480.
Enable this when the output pixel size is set and trimming will match it.
Print size Trim to the aspect ratio of the printing area for the currently set printing paper.
Use this so there will not be any wasted space when printing.
When designating this setting format, you must first complete printer settings.
Fixed size Trim to an aspect ratio of a standard size found on the list.
(3) ./img/ico_trimming01.jpg Apply trimming Automatically adjust trimming area following a format selected from area setting formats.
If the aspect ratio is set, it trims to the designated aspect ratio.
(4) ./img/ico_trimming02.jpg Cancel trimming Return trimming area to initial status.
(5) ./img/ico_trimming03.jpg Trimming tools Switch to trimming tools mode.
(6) ./img/ico_trimming04.jpg Expand trimming Expand so that you can designate all areas recorded in RAW data as subject to processing.

4.13.3. Trimming Tool

Click the ./img/ico_trimming03.jpg icon to switch to trimming tools mode.
Trimming tools are tools that set trimming areas by dragging the mouse on the preview image.
Set a rectangle from the start point of the drag to the end point as the trimming area, following the "Area setting format."

The rectangle from the start point of the drag to the end point will be the trimming area when "Free size" is selected as the "Area setting format."
When other settings are selected, the aspect ratio of the trimming area is fixed. The rectangle trimming area is automatically calculated and displayed from the location of the mouse while dragging.

4.13.4. Expansion of Trimming



With RAW data, information on an area a little larger than the area for development processing may be recorded as a photograph through default development processing. This area is called the expansion area.


Also, whiteout areas caused by "Distortion" from "Rotation / Digital shift" and "Lens aberration controller" are included in the expansion area.

When "Expansion of trimming" is on, the trimming area, including this expansion area, can be set.

The size of expansion areas varies according to the type of digital camera. Also, black areas from no exposure and invalid images such as electronic noise may be recorded, depending on the type of camera.
Blank areas that occur as a result of edited parameters are processed in gray.


4.14. Spotting tool


Spotting tools are tools for erasing spots that appear in photographs.
Its main purpose if to erase things such as when dust on the digital camera's image sensor appears in photographs or spots that appear in images read by a film scanner.

To use spotting tools, either select [Operation Mode (M)] – [Spotting Tools] from the menu or switch to "Spotting Tools" mode from img/ico_spottingtool01.jpg on the tool bar when in the preview display.

A "Spotting Tool" sub-control will be displayed when you switch to "Spotting Tool" mode. Also, a navigation display will appear for the "Spotting Tool" display area on the preview display.

4.14.1. How to Erase Spots

Two methods to erase dust are included in "Spotting Tools": "Auto Erase" mode and "Copy" mode.
"Auto Erase" mode automatically erases spots by clicking on the area with spots. "Copy" mode hides spots by copying designated areas on top of spots.
You can also remove corrections to spots in the "Eraser" mode.

You can combine these two methods. If you are not able to completely erase in "Auto Erase" mode or if you can see traces of the erasures, you can make additional corrections in the "Copy" mode.
You can also make more natural finishes by using the "Eraser."

4.14.2. Operation Methods

Each of the three operation modes, "Auto Erase," "Copy" and "Eraser," are performed by left clicking the mouse over the "Spotting Tool" sub-control's preview display, and in the area inside the circle cursor in each mode.
You can switch between operation modes and adjust the size of the circle cursor while removing spots.

[Operating Mode]
Auto Erase
Copy
Eraser

[Tool effects]
Wide pen
Medium pen
Thin pen

[Other Functions]
Display spotting areas
Initialize spotting areas

4.14.2.1. Operation Modes

You can switch between the three modes, "Auto Erase," "Copy" and "Eraser," while doing your work.
Switch operation modes using the img/ico_spottingtool04.jpg, img/ico_spottingtool05.jpg and img/ico_spottingtool06.jpg icons.

4.14.2.2. Tool effects

The effects of each tool, "Auto Erase," "Copy" and "Eraser," take place within the area shown in the circle cursor.
The effects of these tools are stronger in the center of the circle cursor and weaker near the edges, but you can choose from three degrees of strength.
Switch "Tool effects" using the img/ico_spottingtool07.jpg, img/ico_spottingtool08.jpg and img/ico_spottingtool09.jpg icons.

4.14.2.3. Display Spotting Areas

Emphasize the display of the area to which corrections were added to the image with "Spotting Tools." Turn the emphasis display ON / OFF by clicking on img/ico_spottingtool03.jpg.

4.14.2.4. Initializing Spotting Area

Initialize the "Spotting Tools" parameters by clicking on img/ico_spottingtool02.jpg.

4.14.2.5. Adjusting Correction Size

All three operation modes, "Auto Erase," "Copy" and "Eraser," display the area for corrections as the area within the circle cursor.
The area surrounded by the circle cursor is the range of corrections. Adjust the area of correction for each operation by adjusting the size of the circle cursor.
The size of the circle cursor is designated by displaying "Size" and setting the pixel unit.

In you are in "Copy" mode, you can also change the area to be copied.
The relationship between the area to be copied and the copy location is shown in "Relative Position" and you can set the pixel unit.

You can set and change "Size" and "Relative Position" through three methods.

(1) Change the displayed numerical value
You can change the displayed numerical value of the "Size" and "Relative Position" by adjusting with the spinner or by directly entering in the text box.

(2) Change in the "Size / Relative Position" mode
Enter the "Size / Relative Position" mode by clicking either the "Size" button or "Relative Position" button, or by right clicking.
You can change the "Size" by either dragging the edge of the circle cursor or with the mouse wheel, and the "Relative Position" by dragging the center of the circle cursor with the mouse.

(3) Change by using the [CTRL] key + mouse
You can adjust the "Size" by holding down the [CTRL] key and turning the mouse wheel.
Also, if you are in "Copy" mode, you can change the "Relative Position" by holding down the [CTRL] key and moving the mouse.

Once you are used to these methods, you can quickly change the "Size" and "Relative Position."

4.14.2.6. Changing Display Location / Magnification

The "Spotting Tool" preview display can be displayed from 100% ~ 1600% display magnification.

(1) Change controls on the "Spotting Tools" sub-control
Magnification changes are adjusted with the display magnification slider control. Display magnification cannot go below 100%.
Adjust display magnification with the scroll bar.

(2) Change the preview window's navigation display
Navigation display showing the area of the "Spotting Tools" is executed on the preview window displaying the preview image of the selected scene.
You can adjust the display area by moving the handles on the four corners of the navigation frame and with the center handle.

You can also move the display area of the "Spotting Tools" to the location of the mouse pointer on the preview window.
Display the context menu by right clicking and select "Move Display Location of Spotting Tools."

(3) Change with [ALT] key + mouse operations
You can change the display location and magnification of the "Spotting Tools" preview image with the "Zoom Tool" while holding down the [ALT] key.
You can change the display location with [ALT] key + dragging and resize the display with [ALT] key + [SHIFT] key + dragging.

You can efficiently proceed with your work by arranging the preview window display when using "Spotting Tools."

4.14.3. Notes

Data erased using "Spotting Tools" is saved as a development parameter.
The quantity of this data changes depending on the number of corrections made by "Spotting Tools," but at 10KB ~ 1MB or more, please note that it is quite a large size of data compared to other data.

Correction data from "Spotting Tools" cannot be applied with "Paste Development Parameter." Use the "Paste Part of Development Parameters" function and explicitly designate a "Spotting Tools" category.

"Spotting Tools" data is recorded and saved in automatically saved development parameters and in development parameters explicitly saved with "Save Development Parameters," but they are not recorded and saved in development parameters embedded as JPEG / TIFF EXIF information.


4.15. Image properties


Change properties of currently selected image
Select [Display] – [Image Properties] from the menu. You can also display the image properties button sub-control icon at the bottom of parameter controls.





The "Image Properties" sub-control is also a control for viewing image property information, but there is also a function for simultaneously editing image properties.
If photographic information recorded in the RAW data is incorrect, you can correct it or add information not recorded. You can edit comments here.
You can also add information based on IPTC (International Press Telecommunications Council). You can also make settings that do not record only specific information.
Contents edited here are recorded in JPEG / TIFF images development results by SILKYPIX ®.




Image Properties


4.15.1. File information

File information for the selected image file is displayed.


Editing is not available for items in this category.


Information related to the file format is displayed in "Character Information." Refer to this information when a selected image is not shown in the preview display, because information may be displayed if it is a format not supported by SILKYPIX ® or if the file is corrupted.

"Edit Date and Time" displays the date and time of the latest edit by SILKYPIX. This is the edit date and time development parameter that SILKYPIX automatically records. It is not displayed for scenes that have not had development parameters edited or for initial development parameters.

4.15.2. Data information

This is mainly information recorded in Exif information for RAW data and JPEG / TIFF images. Information related to the image and secondary information on the image is displayed here.
"Comments" are items that can be edited.

4.15.3. Image information

This is mainly information recorded in Exif information for RAW data and JPEG / TIFF images. Photographic information such as camera settings at the time the photograph was taken is displayed here.


"Photograph Date and Time," "ISO Film Speed," "Shutter Speed," "Diaphragm Stop," "Focal Distance" and "Name of Lens Used" can be edited.
You can freely edit items such as corrections to incorrect dates and times set on the camera or when photographic information is not correctly recorded such as when you use a manual lens.


When recording to a developed JPEG / TIFF image, the "Name of Lens Used" is recorded in a standard format to XMP, while other information is recorded as Exif information.


4.15.4. GPS Information

Positional information such as from GPS is chiefly found in information recorded in RAW data and Exif information in JPEG/TIFF images.
It is possible to edit each item.


4.15.5. IPTC

Information is edited based on IPTC (International Press Telecommunications Council). If IPTC information is recorded to RAW data or JPEG / TIFF images under IPTC standards and/or XMP standards, it is displayed as initial values.
If recorded to developed JPEG / TIFF images, it is recorded under a format based on both IPTC and XMP standards.


4.15.6. Editing Items

Some image property items can be edited.
Edited contents are reflected in additional information when saved to developed JPEG / TIFF images.

Utilize this for corrections to image property recorded in RAW data, for adding unrecorded information or if not recorded as additional information when saving developed JPEG / TIFF images.

Items that can be edited have one of the following icons displayed on the right side of "Information." Items that do not show an icon cannot be edited.
Show items that are unedited from their initial values. There are some cases where initial values are not set.
Show edited items.
Show items where the "Do not record when developing" setting was explicitly performed.
This item is not recorded as secondary image information when saving developed JPEG / TIFF images.


To edit an item that can be edited, place the mouse over the item and click on img/ico_property04.jpg displayed on the left side, or double click on the "Information" cell. An edit item dialog will appear.

4.15.7. Edit Item Dialog

The contents of the edit item dialog edit item dialog may slightly differ depending on the image property item, but the following are common operations.

(1) Edit item contents
Set optional item contents. The setting format may slightly differ depending on the type of item.
Enter characters in the text box for characters.
There are also some items for which you can choose values from a dropdown list.
"Datetime" is a special case, so please refer to "4.15.7. Datetime."

(2) Select item contents from edit history
If there are items that can be set with optional values, you can choose item contents from the edit history up set to that time.
Use this if you set the same information repeatedly, such as IPTC information items and the name of your lens.

(3) Initialize
Return to unedited status.

(4) When developing, non-record
Items with this check box checked will not record secondary image information when saving developed JPEG / TIFF images.
Items without initial values set are checked in their initial status.
You can explicitly make a setting for items that you do not want to record as secondary image information when saving developed JPEG / TIFF images.

4.15.8. Datetime

"Datetime" takes special handling, so it will be explained here separately.

The "Datetime" setting is used mainly for corrections to "Datetime" when the date and/or time of the photograph recorded by the camera is incorrect.
The set "Datetime" manages time differences in consideration of correcting the date and/or time the photograph was taken for all photographs taken, such as when the time set on the camera is not correct.
Therefore, you can correct the "Datetime" at one time by editing the "Datetime" on one scene and copying the contents onto other scenes.



Use Change Date / Time of file as the default "Datetime" for image processing images that do not have "Datetime" recorded such as images read by scanners.


In this case "(Date / Time changed)" is added to the end of the "Datetime" item in "Image Properties."

4.15.9. IPTC Information Taste

You can create tastes for IPTC information.
You can easily recall them by recording IPTC information you often use as a "Taste."
Please see "4.1.1. Tastes" for details on how to use tastes.

4.15.10. Register lens name

This function is for recording lens names.
Depending on the camera and lens you use, there may be times when the lens name displayed is different from the lens you use, such as when your lens is from a third-party manufacturer. In this case, you can record the lens name in order to lessen the trouble it takes to change the lens name every time.
Enter the lens name you want to register in the lens item editing dialog and push "Register." Later, the registered lens name will be displayed.
This function can be used only in cases when you can obtain information that can distinguish lens from the image data. There are cases when this function cannot be used, depending on the camera and lens. The edit item dialog for the lens to "Register" will be on when it can be used.


4.16. Editing history

When you edit development parameters, the editing contents are recorded as editing history.
Editing history saves up to 100 items per scene. When the history exceeds this number, old history is deleted and the most recent 100 items are saved.
A maximum of 20 scenes are saved in editing history. When editing the 21st scene, history from the oldest edited scene is deleted and history from the most recent 20 scenes is saved.
However, if operations were performed on multiple scenes, the most recent 20 scenes may have been deleted or there may be no history left.

Protected history is not automatically deleted. Protect history that you do not want to lose through automatic deletion.

Editing history is in effect until the scene for processing is closed. When you close a scene for processing, all editing history for that scene, including protected history, is deleted.
Editing history is deleted when a folder is opened and then the same folder is reopened.

Editing history can by monitored, edited and applied through the "Editing History" sub-control.
Furthermore, you can return or proceed to editing status using the [Undo History] and [Redo History] functions in [Edit (E)] from the menu.


4.16.1. "Editing History" Sub-control


When editing development parameters, additional editing history is added and displayed through the "Editing History" sub-control.
Development parameters are put together for each category and are arranged in an easy to understand format.
When editing in the same category is continuously performed in a short time, such as changes on sliders or spin buttons, the final edited version will be placed in the edit history.


4.16.1.1. Operation Methods

(1) History selection
Restore development parameters for the selected editing position by clicking on the displayed editing item.

(2) History protection
Editing history is automatically deleted when it exceeds the set volume. You can protect history so that it is not automatically deleted.
When you move the mouse cursor to the left side of the editing item to be protected, img/ico_history03.jpg is displayed. You can protect the designated history item by clicking on this item.

(3) Selecting history displayed in reference preview
You can apply the editing history in the reference preview display if the same scene is displayed in the main preview and the reference preview in the multi preview's reference preview mode.
When you move the mouse cursor to the right side of the edit item for display, img/ico_history04.jpg is displayed. By clicking this icon, the designated history item is displayed in the reference preview.

img/ico_history04.jpg, which is always displayed, indicates that the edit item is currently displayed as the reference preview.


4.17. Other


4.17.1. Setting On / Off

Some settings within the development parameters can be set "On / Off." This is found in the "Fine Color Controller," " Lens Distortion Correction" and "Rotation / Digital Shift" sub-controls.
All sub-controls in "Fine Color Controller" and the development parameters divided into three blocks in "Lens Distortion Correction" can be switched on / off.
If parameter blocks are off, they will have equal status no matter what value is used in the development parameters composed of the parameter blocks.

* Please refer to "7.1.4.3. Turning On / Off" concerning conduct when parameters are copied.

4.17.2. Compatible mode



Compatible Mode uses development parameters edited in earlier versions such as SILKYPIX Developer Studio 1.0, 2.0, 3.0, 4.0, Pro, SILKYPIX Marine Photography Pro. 3.0 and SILKYPIX Jpeg Photography 3.0, and is a mode that runs so that development results will be equivalent on SILKYPIX® Developer Studio Pro 5.
Due to the improved development engine on SILKYPIX® Developer Studio Pro 5, results may differ from earlier products even under the same parameters for "Dark adjustment" under "White balance," "Tone," "Color," "Sharpness / Noise reduction," "Highlight controller" and "Fine color controller."
Therefore, we have included a "Compatible Mode" so that you can use the properties of development parameters adjusted with earlier products. If in "Compatible Mode," you can obtain results equal to those of earlier products.

"Compatible Mode" can apply to "Style" and "Sharpness / Noise Reduction." When a "V4 compatible" profile under "Color," you are in "Compatible mode." Furthermore, "Compatible Mode" is also found in "All Categories" of tastes, including these categories.
As an example, results will be equivalent as in earlier products for "Dark adjustment" under "White balance" when "Sharpness / Noise reduction" is in "Compatible mode" or for "Highlight controller" when "Color" is in "Compatible mode."


The tastes of these categories will be displayed in "Compatible Mode (Manual Designation)" if the development parameters adjusted in earlier products are read by SILKYPIX® Developer Studio Pro 5.
Development parameters displayed in "Compatible Mode (Manual Designation)" are recognized as "Development parameters from earlier products" and can be adjusted as "Development parameters from earlier products" as long as you stay in "Compatible Mode."

"Compatible Mode" uses development parameters created in the past with the aim of obtaining development results equal to those output in the past. This can be used when it is necessary to reprint the same photograph.
It is possible to adjust development parameters as "Development parameters from earlier products" in "Compatible Mode," but this usage is not recommended. We recommend that you work after changing to development parameters in SILKYPIX® Developer Studio Pro 5 when you want to adjust development parameters.

(1) For "Compatible Mode"
(a) When image files with parameters edited in earlier products are read
(b) When development parameters edited in earlier products are read
(c) When development parameters in "Compatible Mode" are copied and pasted
(d) When development parameters are adjusted in "Compatible Mode" status
(E) When a taste prepared in earlier products is imported and selected



(2) When development parameters in SILKYPIX® Developer Studio Pro 5 are changed from "Compatible Mode"
(a) When development parameters are initialized
(b) When applying a taste that is not in "Compatible mode"
(c) When development parameters in SILKYPIX® Developer Studio Pro 5 are copied and pasted
(d) When development parameters in SILKYPIX® Developer Studio Pro 5 are read



4.17.3. Dynamic default

This function changes some of the initial values of parameters to values our company deems optimal, based on the model at time of shooting (such as the type of photography elements, size and resolution), as well as information at the time of shooting in the RAW data (such as ISO film speed).
Initial settings for WB shooting information, lens distortion bias from angleof view shading, angle of view digital shift from rotation / digital shift, dynamic range (on some models), sharpness (frame emphasis), NR (controlling false colors, noise reduction), development settings (demosaic sharp) and highlight controller (dynamic range) are dynamically changed.
This is on when initially set parameters are "SILKYPIX initial settings."
Even when other than "SILKYPIX initial settings," prepare partial tastes that do not use dynamic default functions such as WB, sharpness/NR, development and highlight controller, and it will be on if set as initial parameter settings.
By employing this function, SILKYPIX gives recommendations based on information at the time of shooting for the initial settings of each parameter listed above from the status at the time the photograph (RAW data) was read and first opened. Therefore, even when performing finishing work on adjusting parameters as a post-process, you can start from the status of making adjustments that meet each of the shooting conditions so that you can proceed smoothly.


4.17.4. Keyboard and Mouse Operation for Macintosh

This manual is described on the assumption that the mouse has 2 or more buttons and keyboard operation is for Windows PC.
Therefore if you use Macintosh PC, please pay attention for the following;

Right click [Control] key + mouse click is the same as "Right click" of the mouse.
[CTRL] key + Left click [Command] key + mouse click is the same as "[CTRL] key + Left click" of the mouse.
[ALT] key [Option] key is the same as [ALT] key.
