Hello Daniel,

I am also working with Canon CR2 files (Canon 350D). I am sorry, but I have 
deleted your original letter with the problem description. But as far as I 
remember you are having problem with too dark images during raw conversion..am I 
right?
If yes, then: I have the same problem. After opening a CR2, digiKam will convert 
it to a "viewable" image using dcraw. However, let me quote from the dcraw FAQ:

"Why is 16-bit output dark / flattened / unreadable?
     If you want pretty pictures straight out of dcraw, stay with 8-bit output. 
16-bit linear output is the best raw material for professional image editors 
such as Photoshop and CinePaint, but it's no good for most image viewers."

And actually I am only having this problem if I am doing the conversion in 16 
bit mode (8 bit mode is perfect). What I am doing is I set the gamma paramater 
to the maximum once, and after the operation, I rise it a bit again. But this is 
not really a good solution, so I am not doing raw conversion with digiKam right 
now...but I really would like to do all kind of conversion with digiKam.
(please, excuse me if your problem was different. Also I have to mention that I 
am using an svn version that is at least 3 weeks old. Maybe the fresh svn does 
not have the same "effect" during 16bit RAW conversion)

Best regards,
