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. 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.
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 6 to develop them, you can obtain higher quality pictures than the JPEG image which the camera records in taking a photograph.
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.
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.
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.
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.
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.
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 6 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 6 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.
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)
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.
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.
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) 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.
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.
