Dng4ps2 software v0.2.2 and later contains module for camera color matrix calculation. This module compares RAW and Jpeg file and calculates color matrix.
If there is no color profile for your camera or your camera model is not supported by dng4ps2 yet, just take picture of image (which attached to message) from your PC display, compress RAW and Jpeg file and upload it to
zSHARE - Free Image, Video, Audio, Flash and File Hosting or any other servers.
Important! Before taking picture you have:
(with PC)
1. Save my image as file into your disk and open it with full screen mode
(with camera)
2. Select "Program" mode
3. Set best jpeg quality
4. Set white balance to "day light"
5. Switch off all effects
5. Set exposure compensation to -2/3
6. Set focus to infinity
7. Set zoom to middle
8. Set flash to off
9. Set ISO to lowest value
10. And don't take a picture in dark room. Such photos give poor results because of big contrast!
Also I need simple photos taken in RAW (and pair Jpeg too) to test my results.
First results:To test results, download
dng4ps2-0.2.3 and copy values of matrix into 'matrix' option of your camera. All new color profiles are included in last beta version of dng4ps2:
http://dng4ps2.googlecode.comYou can inform me if my results are incorrect. I will try to recalculate it again.
Values of matrices are shown in 'dcraw' order.
