6. Useful Functions for Adjustment

6.1. Highlights, Shadows and Out of Color Gamut Warning

This software has warning functions to support parameter adjustment.

When you click the ./img/ico_whitealert.jpg button on the toolbar, you can enable each warning.
In addition, if there is a check at [View (V)]-[Display warning]-[Flash warning] in the menu, warning displays will flash on the image in the preview display.
If there is no check the warning display is always displayed.
(Soft proofing is always displayed.)

(1) Highlight warning
The portion where highlight or color is saturated blinks.
The portion where highlight is saturated blinks in black, and the portion where color is saturated blinks in negative color.
This function is convenient for adjusting "exposure bias" and for adjusting "saturation" of color.

(2) Shadow warning
The portion where the shadows are underexposed blinks in white.

(3) Highlight/Shadow warning
This feature gives both the highlight warning and shadow warning simultaneously.

You can customize these warning levels. Please refer to ' Threshold of highlight warning' and ' Threshold of shadow warning'.

(4) Out of color gamut warning
This feature gives a warning for the portion where the color is outside of the color gamut. It means that the saturation in this portion is to high.
Please refer to '10.1.6. Color Gamut and Adjustment Outside of Color Gamut'.

6.2. Histogram

The menu command [View (V)]-[Histogram (H)] displays the "Histogram" sub-control.

Histogram displays a brightness distribution on a picture.
You can check which part of the picture has what level of brightness. The horizontal axis shows brightness (0-255), and the higher the value (right side), the greater the brightness.
The vertical axis shows the number of pixels that corresponds to relevant brightness level. R,G, and B are displayed in each color on a graph, and the place where these overlap it is displayed as an additive color mixture.

6.2.1. Display of Histogram

The arrow displayed on the gray scale at the bottom has the following meaning.

(1) Contrast center
This indicates a contrast center of tone.

(2) RGB marker
This displays RGB value at the point where the mouse cursor is on. The value corresponds to the brightness position on a graph.
It is very effective to check where a color of a point on a screen is distributed on a histogram.

(3) Channel
You can display the histogram of any channel of RGB.

In addition, by clicking a graph, you can see each brightness statistic of the RGB.

Lv is the value given to brightness (0-255) shown on the horizontal axis. "R", "G" and "B" are the statistical values for RGB in percentage (%) units.

If the histogram of the image is evenly distributed for each RGB value (Lv value), the value for each statistical value 0-255 will be 1/256 = 0.39%.
For normal photographs, most of the area will be in the range of 0.00-2.00, but brightness distribution may be consolidated in a photograph whose subject is almost a single color, such as completely dark photographs and macro shots of flowers.

6.3. Navigator

The "Navigator" is a guide display for places displayed on the preview screen for the dedicated thumbnail.
You can change the position of the display by dragging the guide on the "Navigator" in tool modes other than Fitted display, such as Zoom tool, Loupe tool or Palm tool.
In addition, you can expand or shrink the preview with mouse wheel operations on the "Navigator".
The Navigator is not displayed when in thumbnail mode because this is effective only when in the preview window is displayed.

6.4. Shortcut Keys and Function Keys

Shortcut keys and Function keys that you can use in SILKYPIX® Developer Studio 6 are shown below.
* These are default settings, and you can customize the keys. Please refer to '9.4. Shortcut keys settings'.
* When your OS and SILKYPIX use the same shortcut keys, SILKYPIX® may not be operated by those.
In such case, please change those of your OS or SILKYPIX®.

6.5. How to Use Storerooms

In the "Tastes/Parameters" sub-control, there are convenient ways to store and paste the development parameters.

6.5.1. Copy Development Parameter

A basic method of operation is described in "7.5. Copy Development Parameters to Storerooms" and "7.6. Set Development Parameters to Multiple Images".
This function is used to apply the development parameters, which are adjusted and set for one image, to other images. This is the same function as copying and pasting the development parameters. However, This function can store the four development parameters simultaneously.

6.5.2. Save Development Parameter Temporarily

The development parameters are determined after having finished adjustment. But it is sometimes necessary to temporarily record the development parameters on the way of adjustment.
Because if you have the temporary parameters, you can restart to adjust the parameters from the point where you lost the way, not from the beginning.

6.5.3. Compare Development Parameter

The "Storerooms" can save not only the development parameters but also developed images, temporarily. When using this feature, you can compare two developed parameters.(*1)
The two parameters are temporarily registered And then you can compare the image switching the parameter.
We recommend you to use the this function in the "Zoom tool" mode. Then you can enlarge the portions of the whole image and compare them easily.

*1 To utilize this function maximally, you need to set "Standard" or "Maximum" in "Cache settings" on "Function settings" dialog.
Please refer to ' Cache settings' for the setting. Please understand that using this function will maximize usage of memory.
