nikopol, did you test other color profile for A710? Does it show good result?

I uploaded setup of dng4ps2 software with new matrices here: http://dng4ps2.homeftp.org/dng4ps2-0.2.2matrix.exe so you can use other RAW converter (not only dcraw) for developing your photos.

Hm ... is there a simple way to change the color matrix in DNG4PS-2 (other than reconpiling the program)? Current version doesn't use header files at all, everything is hardcoded in the program

May be I will do ability to configure matrices for DNG4PS2

I have tested the program given at the link for the A570IS. This solution seems to work verry well! Thank You!

Btw, can you upload one or two images (RAW and Jpeg files) from A570. I need it to check my results

If you still need them here are two daylight images
img.zip - 20.49MB
and one flash image
img2.zip - 7.45MB

Here's a couple of test shots with IXUS 950 (SD 850) 1.00C, ixus950_sd850_raw_test.rar - 16.07MB. I reckon it should have the same profile as A720 and S5 IS. Physically the same sensor, right?

Thanks for images! I calculated color matrix, inserted your camera model into DNG4PS2 and reuploaded it here: http://dng4ps2.homeftp.org/dng4ps2-0.2.2matrix.exe. You can test

Thanks ArtDen, looks better than everything I tried before. Would you post the matrix, so that I can play with it, compile dcraw? And -- is it really different from what you find for A720 ans S5 ?
