Hello,

thanks for you answers. In between I solved the problem. The source of trouble 
was really the ADOBE RGB colorspace that had been used for the photos of my 
friend.  I converted all of them to sRGB. The only thing I had to else then 
was to reduce saturation since all photos were clearly oversaturated after 
conversion to sRGB.  

Since i did not see a batch feature for this in digikam (I had about 300 
photos) I used bibble for this after all, where this could be done with a 
select all photos keyboard shortcut 1 more mouse click to adjust saturation 
and another key press to start conversion.  Now digikam displays the jpgs 
correctly and I can stay with color management turned off. 

I think for digikam it would be helpful to have a way to look at a photo in 
another color space where digikam should convert colors on the fly (without 
changing the photo and trying to write it to disk and a batch conversion that 
can do this for all photos at once.  

Thanks
Rainer
