The product concept of SILKYPIX Developer Studio 9

It is a standard version of SILKYPIX series recommended for people of a wide range, from people who are going to start Raw development and those looking for new RAW development software.

SILKYPIX Developer Studio 9: New features

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”:
  2. If the proper lens profile cannot 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.

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.

Enhance cooperation with external applications

By pressing the “Open with another application” button newly created on the toolbar for the image adjusted / edited with this software, it is now possible to develop in real time and open it with another registered application in advance. It is effective when you want to seamlessly work on retouching such as clipping or compositing from RAW development.

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 with 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.

Feature of SILKYPIX

“SILKYPIX Developer Studio” is a RAW development software which develops a photograph satisfactorily with high quality image. Far using powerful computing power of PCs and let’s consider how we can get high quality image. Conventional, digital camera-specific disadvantages that had been thought to be helped are, for example, unnatural edge in the high-saturation color boundary, false color ride to the fine structure part, or noise in high-sensitivity shooting. These disadvantages were thoroughly suppressed and SILKYPIX satisfies both of the demand for high resolution and high color separation performance. We are aiming a smooth and natural photo image like a silk. This is the origin of the name of SILKYPIX.
