0.2. What is SILKYPIX?

This SILKYPIX software generates images by processing RAW data recorded by the digital camera. (*1)
This process of generating an image by processing RAW data is called “development”.

RAW data is the unprocessed data recorded as digital light energy information that image sensors capture. Compared to normal JPEG files, RAW files are bigger in size because native information is recorded at the time the photograph was taken.

When photographs are taken in RAW e.g. when photographs are saved as RAW data, you will be able to perform more varied image processing from the unprocessed light energy information even after taking the photograph.
The role of SILKYPIX is to get the most out of the photographic merits of RAW and to draw out as much image information as possible when reproducing scenes shot in RAW data. SILKYPIX was developed to make this a reality.

*1 … JPEG/TIFF files can be developed. For more details, please refer to ‘2.4. How to Handle JPEG/TIFF Image’.

0.2.1. Basic Image Adjustment Items

In this software, you can adjust various parameters of development procedure.
Basic development parameters will be introduced here.

  1. Exposure bias
    You can adjust parameters at the development process with SILKYPIX Developer Studio Pro9 / 9 and obtain the same effect when using the function of the camera.
    Also, you can use a high-precision “automatic exposure bias” feature, which makes it possible to drive into correct exposure quickly.

  2. White balance adjustment
    You can obtain results comparable to photographs taken with appropriate white balance settings on your camera by adjusting parameters when you develop them.
    You can also obtain results comparable to photographs taken using color temperature conversion filters by adjusting parameters when you develop them.

  3. Sharpening / Noise reduction adjustments
    You can emphasize the outline of a shot image, or change the noise reduction during the development process.

  4. Tone Adjustment
    You can change the tone of the target scene (soft or hard, etc.) during the development process.

  5. Saturation Adjustment
    The “Color representation” enables you to treat an image like changing reversal film, even after taking a photograph.

  6. Lens aberration controller
    You can correct or reduce shading (when surrounding light quality is low), distortion and magnification aberrations from a peculiar lens, and create images of a higher quality.

  7. Rotation/Shift lens effect
    If you find pictures you took with a camera that was tilted, you can adjust the angle by using the “rotation” function after taking a photograph.
    In addition, the “Shift lens effect” function has the same effect as using a shift lens which enables you to control the perspective and to shoot a building effectively.

0.2.2. Features of SILKYPIX

When you store image data as RAW data and use this software to develop them, you don’t have to worry much about adjustments during taking the picture because you can do most corrections at the development process stage.
The merits of recording and saving to RAW data compared with saving in JPEG / TIFF are that information is not processed and the amount of information recorded is much richer.

It is also possible to readjust photographs recorded and saved as JPEG / TIFF with this software.
However, compared to RAW data, there is less information recorded because JPEG / TIFF images convert to a special color space (sRGB, Adobe RGB, etc.) and color gradation converts to 8bit = 256 steps.
Therefore, if you readjust photographs saved as JPEG / TIFF, the breadth of adjustments are narrowed and deterioration of the image from the adjustments becomes greater.
In order to adjust images while maintaining high image quality, it is necessary to save the RAW data when taking the photograph.

By saving to RAW data and developing with this software, you will be able to obtain very similar results when developing after taking the photograph, as when color and image quality are adjusted at the time the photograph was taken.
SILKYPIX greatly shortens the time spent shooting and increases the chance of capturing that important “moment” on the camera.

In addition, with the adoption of a high development algorithm, SILKYPIX has the following features.

  1. High resolution, High resolving power
    Although it is generally considered that resolution is decided by the type of lens and the number of pixels of the image sensor, a key factor of actual image resolution is the demosaic process during development procedure.
    When you select RAW data to record images and use SILKYPIX Developer Studio Pro9 / 9 to develop them, you can obtain higher quality pictures than the JPEG image which the camera records in taking a photograph.

  2. Advanced color separation
    When photographing with a digital camera, the color boundary in high saturation area is lost and becomes white outline, which is a specific phenomena of digital cameras.
    This effect called digital haloing is caused by the white outline through the phenomena that occurs when color resolution is low compared to excessive brightness.
    We have therefore created a completely new demosaicing logic and embedded it into the software in order to provide advanced color resolution. This logic allows delicate and advanced color resolution.

  3. Less false color
    Most of digital cameras now have sensors with a structure called Bayer array.
    The R, G, and B sensor elements are allocated in order of Bayer array flatly. Each sensor can only capture one of the R, B or G, so false color appears on the edge of picture or area including delicate pattern.
    The software reduces this false colors highly effectively with advanced pixel value forecast logic.
    Fundamentally, high resolution, high separation capability, and false color reduction are not realized at the same time logically. High resolution causes increased false color phenomenon, and a trail of false color reduction results in low resolution.
    However, the software efficiently enables the realization of these processes simultaneously to create natural pictures and colors.

  4. Color noise reduction at high sensitive photography
    When photographing in high sensitivity mode for night photography or in a dark place, noise of the image sensor generates color noise spots on the image, which is specific to digital cameras.
    These color noise spots appearing irregularly on the picture are very unpleasant to the eyes, and supposedly many photographers avoid high sensitive photography because of this phenomenon.
    The software provides a function for reducing the color noise that surprisingly creates clean pictures for high sensitive photography.
    With this software, you can select a wide variety of photographic methods and objects to create a new photograph.

  5. Hue control for highlight area
    The software has the function to reduce color reverse or overexposure (bleached-out looking) in the highlight area.
    For example, when taking a picture of a person, if you increase a development gain to make a skin color white, color shift phenomenon occurs and highlight boundary area often becomes yellow.
    The Highlight controller of the software enables color control in over exposed area and creates fine color adjustment in these highlight areas.

  6. Real color reproducibility with high linearity
    In order to create accurate colors with various types of light sources, we have embedded our unique color matching logic based on multiple color matching data acquired in many test pictures.
    Many types of light source with various spectral distributions, such as sunlight (natural light), fluorescent light, tungsten filament lamp, glow of sunset, electric flash and combination of them are supported, which realizes accurate color reproducibility.
    Based on this color reproduction, you can utilize “3-dimensional color mapping methods”, which converts colors into 3-dimentional data to create (Memory color) expressing similar colors with the colors in a human’s memory, (Portrait color), expressing highlights of the skin, and Film taste expressing colors in a positive (Film color)“. You can use these color modes according to its utilization or picture image.
    Also, ‘4.10. Fine Color Controller’ can change the precise color and to control the delicate color.

  7. Highlight reproduction control by the “dynamic range compression”
    The “dynamic range” control function allows you to make the best use of RAW’s ability, which has enough “dynamic range” and records whiter energy than the white point.
    You can obtain the smooth gradation in highlight area similar to film.

0.3. Difference to Other Photo Retouching Software

RAW development process with SILKYPIX Developer Studio Pro9 / 9 and image processing with a photo retouching software are similar.
While various types of photo retouching software that support RAW data are increasingly available in the market, there is a critical difference between them.
Understanding of the difference helps you to use SILKYPIX Developer Studio Pro9 / 9 to its fullest.

The important point is that this software always starts every image processing function based on RAW data.
When you change parameters in image processing (for example, changing “Exposure bias”, “white balance” or “saturation”), the software always starts processing based on RAW data.
Development parameters are recorded in separate files different from RAW data.
Therefore, although the workload for the computer increases, you can obtain a lot of benefits described below.

  1. RAW data is not modified (non-degrading image processing).
    Original image data is never changed, so you don’t have to worry about losing it even if you make a wrong operation.
    The basic design of this software is to “not modify RAW data files”.
    If JPEG files recorded on a camera are processed with photo retouching software or digital camera editing software, there is a chance that the original image will be overwritten, but with this software the original data file is not modified. (*1)

  2. You can change parameters until you’re completely satisfied
    In photo retouching software, images are processed through independent procedures, proceeding in order, one by one.
    For example, if you want to change brightness and then adjust color balance, you have to create the image with a new brightness level and then adjust color balance of the newly created picture image.
    Adjustment work proceeds while checking each result.
    If it is necessary to make minute adjustments to brightness after adjusting the color balance, then you have to choose to either start over again from the beginning or make the image at that time even brighter.
    Using the first method will not degrade the quality of the image, but it is that much more trouble. The second method is accompanied by image degradation.
    Always having to start over again is not actually realistic, and in most cases a certain degree of image degradation is allowed and work proceeds.
    The user’s technique is shown in how he or she lessens degradation in image quality and adjusts the image to fit the purpose.
    With this software, image processing always takes place in the optimal order after reading the RAW data.
    If development parameters are determined, development results will be the same and there will be no degradation to image quality, whatever sequence is employed until adjustments are concluded.
    Whether you adjust the white balance after adjusting exposure or adjusting exposure after adjusting the white balance, if the final parameters are the same, the results will be the same.
    Therefore, you can change the parameters a number of times until you are satisfied with the result.

  3. There is no degradation in image quality from adjustment procedures.
    If you make adjustments through photo retouching software, the adjustment procedures will have an influence on image quality.
    You have to decide which one should be adjusted first, brightness or color balance. You also have to consider when you should adjust: Sharpening, Tone curve, and Color space for working or the Lens aberration controller.
    Always performing these in the optimal procedure demands a high degree of knowledge which to the lay person may result in excessive image quality deterioration.
    In addition, even if procedures are appropriate, there are times when gradation or a part of the color gamut is lost due to the combination of procedures.
    This software is designed so that image degradation like that through other photo retouching software will not occur, through internal processing that appropriately combines high-grade pipeline image processing that can transmit pixels brighter than pure white.
    Leave the image processing order up to SILKYPIX.
    Whatever order the adjustments made to development parameter are performed, SILKYPIX will output development results of the highest quality through optimal image processing.

  4. You can restart adjustments whenever you want
    Development parameters are automatically read and updated for each image, and are managed in a file separate from the RAW data. (*2)
    Therefore, you can later readjust development parameters from the previous adjustment results.
    Development parameters are also concealed in JPEG / TIFF images that saved developments.
    The development parameters buried in these developments can be viewed with this software and applied to other images for processing. (*3)(*4)
    If you have the developed JPEG / TIFF images and the original RAW data, the development parameters for the development results can be read and minute adjustments can be made from the previous adjustment results at any time.

  5. Perform efficient image adjustments.
    After image processing based on parameters that were set is complete, photo retouching software performs the next image processing, so image processing is complete at the stage when all adjustments have been completed.
    With this method, in order to go through multiple image processes, you must wait until the previous process is complete, which means that there is a lot of wait time until image processing is complete.
    With this software, development processing is gathered for later and can be processed as a batch.
    You can use a workflow in which development parameters are set while looking at a preview image and development processing is performed later in a batch.
    In order to efficiently adjust images, a preview image makes full use of simple image processing and partial development processing, and it is displayed quickly.
    Even if one image processing has not completely finished, there are many times when making the next adjustment to development parameters is possible, so less time is wasted waiting for the next development parameter to take effect.
    Even if a certain amount of time is necessary for actual development processing under the final development parameters, the work can be performed efficiently until the development parameters take effect.
    This workflow shows its power when processing large quantities of pictures at the same time.

*1 It is possible to rewrite rotation information tags, depending on the settings, on JPEG / TIFF / DNG images.

*2 Development parameters are automatically recorded in a “SILKYPIX_DS” sub-folder created within folders that contain RAW data for editing and JPEG / TIFF / DNG images.

*3 Development parameters are buried within the Exif information in JPEG / TIFF images that record development results.
They will not be buried if not recorded with Exif information.

*4 “Spotting tools” information is not included in development parameters buried in JPEG / TIFF images that record development results.

* From an early stage, our company developed this kind of “non-degrading image processing” (named OIP technology by our company) and adopted it for many products beginning with digital camera software called “Daisy Digital Camera Friend” which was sold in 1999.
With SILKYPIX Developer Studio Pro9 / 9, we have applied the technology to such processes that irregular images like Distortion Correction and, Digital Shift and implemented a completely continuous image processing in those processes.
The process causing rotation and deformation of image must be usually executed after development, however, this software allows users to skip this step and enables a complete set of smart workflow from the basic adjustment, such as exposure and white balance, to lens aberration correction.

0.4. Differences with conventional products

The following is an explanation of functions that have been added / modified since “SILKYPIX Developer Studio Pro 8”.

  • Equipped with Dehaze function
    Add the “Dehaze”slider to the adjustment item for the mist removement of hazy images caused by atmospheric moisture or vapor.

  • Adjust brightness of highlight/shadow individually
    The “Highlight/Shadow” slider is mounted in the exposure adjustment item.
    This makes it possible to individually adjust the brightness of light and dark areas in the image.
    Even in scenes where subjects with dark contrasts are difficult to shoot or exposure scenes might be difficult to control, the brightness adjustment can still be fixed afterwards by individually using the “Highlight/Shadow” slider.

  • Lens aberration correction function is easier
    “Lens profile” function has been added to the lens aberration correction item.
    Automatically select the appropriate lens profile (*1) from RAW data information, and perform the optimum distortion correction for the combination of camera and lens. (*2)
    In addition, it has a distortion correction function using simultaneous recorded JPEG images.
    Correction equivalent to the lens correction (distortion correction) processed in the camera with respect to the JPEG image recorded at the same time is also applied to RAW data. (*3)

    *1 We use the lens database attached to “Lensfun” which is an open source library performing lens correction based on lens information in the lens profile.
    Please refer to the official page of “Lensfun” for details of the lens profile. (Link to “Lensfun”: http://lensfun.sourceforge.net/)

    *2 If the proper lens profile can not be specified automatically, it will be set manually.

    *3 This function can only work when JPEG / RAW simultaneous shooting is performed with lens correction set to “ON” on the camera side and JPEG / RAW is saved in the same folder.

  • “Blurred/sharp periphery” function added
    The “Blurred/Sharp periphery” function is added to the effect adjustment item.
    Using this tool, users are now able to blur the periphery of the specified range and apply sharpness.
    You can create a close-up effect by blurring the surroundings of the subject that is the main subject in “Blurred periphery”. You can make a good correction using “Sharp periphery”, etc. when shooting with the aperture stop value of the lens and the peripheral resolution drops.

  • Function enhancement of partial correction tool (Curve / Polygon area selection, Select color to be corrected)
    “Curve / polygon area selection” has been added for selecting the correction area of the partial correction tool.
    “Curve / polygon area selection” can be set by clicking the area to be partially corrected in the image and connecting it by a curve or a straight line. That makes it very easy to select even a complicated area which used to be difficult before.
    In addition, it is now possible to click “Select color to be corrected” that allows you to adjust only specific color gamut within the region as a correction target by selecting all correction regions including Circular/Gradual correction filter and brush.
    By utilizing “Select color to be corrected”, it became possible to select more complicated correction area, and it was also possible to easily create monochrome photographs of only a partial color.

  • Adding an automatic adjustment button
    We have newly added the “Auto Adjust” button which performs [Auto exposure bias], [Auto White Balance Setting], [Automatic level correction] suitable for each image at the same time.
    The “Auto Adjust” button is recommended for those who are “to start RAW development in the future” or “RAW development has many adjustable items, so you do not know what to do with hands”.
    Also, when adjusting a large amount of images at once, you can improve the efficiency of the adjustment work by utilizing the “Auto Adjust” button.

  • Improvement of noise reduction (Level of shadow noise reduction)
    The adjustment item of “Level of shadow noise reduction” has been added to the adjustment item of noise reduction.
    In the latest SILKYPIX noise reduction, processing of the latter is optimized for each of the bright and dark parts of the image in order to achieve a higher image quality.
    However, rarely in RAW adjustment, the noise in the dark area may be conspicuous due to the exposure correction and sharp adjustment.
    Side effects, for example that the entire photo may be blurred will occur if the “noise removal” is strengthened with the “Smoothness” slider. Instead of this procedure setting the “Level of shadow noise reduction” of the new function, dark noise Removal can be applied.

  • “Search in thumbnail” possible
    “Search in the thumbnail” is an easy way to search and display images by designating conditions such as file name, shooting date, comment or rating information from the specified folder.

  • Further improved operability
    Independent arrangement of “initialization button” instantly returning the image to the state before adjustment.
    Added new color to “User mark” convenient for image selection etc.
    Added “Open in another application” that allows you to easily transfer images from SILKYPIX to retouching software etc.
    New construction of “control pallet” which can arrange multiple sub-controls collectively, Items related to operability such as “Customize toolbar” have been improved.
