I've updated my article here: http://blog.pcode.nl/ But this is the command-line that has been working the best for me: # scanin -v -p -dip canon.tif it8.cht R080505.txt # colprof -v -A "Canon" -M "EOS 400D" -D "Canon EOS 400D (daylight)" -C "Copyright (c) 2008 Pascal de Bruijn. Some rights reserved." -r 1 -q u -a S -n c canon I have tried -a G as well, but a shaper seems to give better results. Also there only a small difference between -a S and -a s, though a single shaper looks slightly better to me. Regards, Pascal de Bruijn
