hello Graeme, thnx.. 1) but shouldn't the profile generated by dispcalGUI / argyll account for making the non-zero display black equal to the black in the image? (see 'Black output offset' paragraph in http://dispcalgui.hoech.net/). Maybe I'm mixing up things.. 2) I also read this: http://www.argyllcms.com/doc/CrushedDisplyBlacks.html It seems to work, the darker tones look normal, but the saturation of the colors decreases a lot 3) can you recommend a color managed image viewer (or editor) that you know and use yourself, that I can try to see how the profiles work ? kind regards josvanr On Sat, Dec 24, 2011 at 5:15 AM, Graeme Gill <graeme@xxxxxxxxxxxxx> wrote: > Jos van Riswick wrote: > > I . supplied with argyll..... > > Hi, > it's hard to comment specifically about an application > (Gimp) who's color management details I don't know.
