I'm making 2 profiles from the same shot of IT8 target with dSLR. After scanin I run colprof twice - once with -r 1 -q m -a X and second time with -r 1 -q m -a S parameters. When I look at the shape of the profiles in gnome color manager, they are different! The ratio between RGB channels differ. Should it be so or I'm doing something wrong?
You've chosen different profile representation types, so of course the result is different ! (One of the problems with -aX is that you can't be sure which table is going to be used, the XYZ cLUT, or the shaper/matrix.) Graeme Gill.
