Hello ArtDen,

I put the SD700 calibration pix (JPG + CRW, plus 2 extra ones for verification) in:

Thanks in advance,

mkmenuts

P.S. - Is that calibration matrix CCD dependent only (which means several cameras share the same one), or are there more variables involved?

mkmenuts, I will try to calculate color matrix this evening. Color matrix, calculated for your SD700 is usable for all other SD700 cameras :)

Matrix for SD700 was added. Can't calculate matrix for A630 as colors are oversaturated.

I find no sense to convert G9 RAW files with dng4ps2 as they already contain good EXIF info, good color matrix and can be processed by native software or other RAW software (RawTherapee for example)

Sorry for double post but I can not edit the last one.

I installed my old Eizo CRT and I took another set of shots. I see a big difference between crt colors and lcd colors. Here: http://www.filefreak.com/pfiles/40442/A630%20w%20crt.rar, you can find the last shots with the descriptions in the archive.

ArtDen, are there any chances for DNG4PS2 with possibility to modify matrix ?
I don't need any graphical interface, it would be enough for me to have all matrices in one text file, for example in format

A610  n1 n2 n3 ... n9
A620  n1 n2 n3 ... n9
A630  n1 n2 n3 ... n9
etc ...
