Yes.

Gerhard,

About handbook, ICC profile settings and RAW workflow need to be explained 
very well. It's not a simple task to do. I have some idea. We will do it at 
the right moment, later. I need to have a clear mind (:=)))

But to resume this thread, we can said tha sometimes camera maker profiles 
work fine (Minolta for example), sometimes no and investigations are require 
to find the right files.

Other susject that nobody have talk in this thread is the icc profile file 
auto-selection, according with 'make' and 'model' Exif tags (like UFRAW has 
planed to do)

This way require a camera icc files repository with all camera profiles that 
the digiKam users need to use (if he has more that one camera)

A setup table is require where the user set witch profile need to be use with 
'make/model' Exif tags found in image (JPEG, RAW, TIFF/EP). When you start 
image editor, digiKam look in this table and choose the right profile 
automaticly.

I have planed to do it later 0.9.0
