I have had problems with some Dell monitor profiles, which LCMS 2 renders too dark. One example is here: http://support.dell.com/support/downloads/download.aspx?releaseid=R230160&fo rmatcnt=1&libid=0&fileid=331763 This is an EXE file, but you can rename it to a ZIP and extract it. I can also post the profile if that is easier for anyone. My guess is that the culprit is the shitty tone reproduction curves in the profile. Nothing else looks suspect to me. Just to check that I'm not complete nuts, here are some tests from transicc (v2) and icctrans (v1.19). ***** LittleCMS ColorSpace conversion calculator - 4.0 [LittleCMS 2.00] Enter values, 'q' to quit R? 10 G? 10 B? 10 R=1.6304 G=1.6304 B=1.6304 Enter values, 'q' to quit R? 20 G? 20 B? 20 R=3.7471 G=3.7471 B=3.7471 Enter values, 'q' to quit R? 255 G? 255 B? 255 R=255.0000 G=255.0000 B=255.0000 Enter values, 'q' to quit R? 30 G? 30 B? 30 R=6.9650 G=6.9650 B=6.9650 **** LittleCMS ColorSpace conversion calculator - v3.3 Enter values, 'q' to quit R (0..255)? 10 G (0..255)? 10 B (0..255)? 10 R=4.10 G=4.10 B=4.10 Enter values, 'q' to quit R (0..255)? 20 G (0..255)? 20 B (0..255)? 20 R=9.42 G=9.42 B=9.42 Enter values, 'q' to quit R (0..255)? 30 G (0..255)? 30 B (0..255)? 30 R=17.48 G=17.48 B=17.48 **** The results from v1 is consistent with color engines from ACE (Adobe) and ICM (Microsoft). I was too lazy to check Apple's engine.
