Version: 0.9.0-beta1 (using KDE KDE 3.5.2) Installed from: Gentoo Packages OS: Linux I can't say I really understand colourspace issues, so I'm actually not sure if this is a bug or a feature, but... The sRGB profile supplied with digiKam uses the white point D50. It seems that D65 is the standard white point for the sRGB space. The implication of this is that if I use the workspace profile supplied with digiKam, I get very warm whites, whereas the use of other (HP/Microsoft) sRGB profiles results in neutral whites. What is the rationale for using a sRGB profile with a D50 white point?

Perhaps we can change this sRGB icc file from D50 to D65. The current file come from krita repository. We just need to have a free for use icc file. Some urls welcome... Gilles Caulier
I'm going to close this bug and marked as INVALID, since really, this is not a bug (see https://bugs.kde.org/bug_status.html about "resolution state"). If anybody has something else to say about it, please feel free to reopen it. Gilles, if you think the new state is a wrong one, please change it. Paco Cruz
Adobe has a package of royalty-free ICC profiles that can be bundled with software. It includes AppleRGB, Adobe RGB, ColorMatchRGB and sRGB, as well as a number of CMYK profiles. Please see http://www.adobe.com/support/downloads/iccprofiles/iccprofiles_linux.html for the licence and download. It seems that this is the same sRGB profile used in LittleCms. LittleCms also has another, apparently more comprehensive profile made by Microsoft and (AFAICT) in the public domain. This could be obtained from the LittleCms tarball.
Well, what do you think about Adobe Bundling Agreement ? The sRGB they provide is called "sRGB IEC61966-2.1". On this page : http://webstore.iec.ch/webstore/webstore.nsf/artnum/025408 "sRGB IEC61966-2.1" is called "Default RGB colour space - sRGB". So, I find confusing to have a different sRGB in digikam. Before seeing this bug, I thought there could be only one sRGB. Which one is really the internet standard ?
I guess the answer to the last question is "sRGB IEC61966-2.1" because firefox show the image with different colors than displayed by showfoto in showfoto's embeded sRGB. So, perhaps it would be a good thing to remove showfoto's embeded sRGB or rename it in something like "sRGB - D50".
Agree to rename this file like D50... Paco, we can add the other sRGB profile D65 into digiKam, like Krita or Photoshop have. The file is in krita repository. Gilles
