Hi ArtDen. Can you make a profile for TX1?

I took the photos in "Manual" mode as I presume that is "Program" mode and you did not mean "Auto"
I did not understand the compression stuff so I just uploaded them as is as compression did not seem to do much:

zSHARE - crw_1357.crw

zSHARE - img_1357.jpg

If I am completely stupid and wrong, I will do it again for you.

New beta release http://dng4ps2.chat.ru/index_en.html#download contains possibility to change color matrix in program options (see attached screenshot).

Another features are:
1. It is possible to edit camera profiles
2. Calculated color matrix is stored automatically in camera profile (button 'Save' in calibration window)
3. Camera type detected automatically from jpeg exif

Try 0.2.3beta2: DNG4PS-2 . It contain support for TX1. Color matrix is not very good, but I think it is usable for the first time.

I see, but it's a little reddish for me!
Is there a way to tell dng4ps2 using a copied profile (my custom S5 profile) instead of automatically choose the default S5 profile? I use conversion with jpg to keep exif

lukg, you don't have to copy profile. Just change color matrix for existing S5 profile.

May be this is too early to request, but if any A720IS owner calculates calibration parameters in ACR for daylight,
it will be of great help. This has to be done by photographing color charts in daylight, not by comparing the raw with the jpeg,
as the jpeg has few inaccurate colors. Same request for other cams too!
