Gerben, this bug should be fixed with KDEs 4.5.4 libkdcraw (blacklevel processing). Which camera do you use (for verification)? Best, Jens On 06-12-10 10:07, Jens Mueller wrote:

Sony A700
Can I download the latest libkdcraw somewhere so I can compile and test it?
thanks,

I use A500 and A450 at home, and i confirm that ARW file problem is fixed with current implementation from svn... Gilles Caulier Currently i work on this version with new demosaicing methods : http://websvn.kde.org/branches/extragear/graphics/libkdcraw/ It will be released with future KDE 4.7 But current code from svn is enough : http://websvn.kde.org/trunk/KDE/kdegraphics/libs/libkdcraw/ It will be released with next KDE 4.6 Gilles Caulier KDE 4.5.4 is already released (http://kde.org/announcements/announce-4.5.4.php), perhaps you distro provide updated versions, too.

Yes! I can confirm that with the svn code of libkdcraw the problem is gone.

Created attachment 54185 [details] This is a dng from an .arw file. Version: 1.6.0 (using KDE 4.5.1) OS: Linux An ARW file which has the luminosity channel graph in the Image Editor nicely streched over 4/4 of the graph, gets converted to a DNG file which has the luminosity graph start at 2/4. The picture looks brighter, has less contrast and also seems pink-ish. Reproducible: Always Steps to Reproduce: use dngconverter to convert a sony .arw file Actual Results: brighter, less contrast, pink-ish image Expected Results: create identical image I hope I do something wrong but can't find it.
