Yes, looking at the sheet, then 3) looks best. This is an optical effect due 
to enhanced contrast and slightly darker. But the hue is too "greenish" and 
details in the shadows (hair, bra, shoes) drop. So compared to the original 
no. 1) comes closest.

I've played around with different combinations of the bibblelabs profiles and 
I have the general impression that there's almost always too much green, but 
I'll have to take more time for more serious testing. Soon.

At least now the basic problem is solved for me. Now it all depends on finding 
(or making?) the right profiles.

Gilles:

when I play with color->color management and choose a "wrong" profile (like an 
input device profile for working space) digikam crashes. Is this a bug, shall 
I report it to the bugs list, or a problem of my install? The crash is 
reproducable here.

have a nice evening, and again: thanks for the help!

Daniel
