I had updated the source this morning (and update exiv2 too, I sent a 
message on the group for a compilation problem) ...
Anyway it really it's too slow in my computer (just resizing the window 
takes few 3/4 seconds, and it's quite annoying), I noticed the 
difference in colors if I use it or not, and if I work on levels and 
curves I would expect to work on "real" colors...

I would really appreciate that... :) I think that digikam is almost 
self-explanatory,
and it has really simplified things for the color management, but I'm 
particularly dumb and
I've always failed to understand how to exploit the color-management in 
the workflow...

I followed the evolution of digikam from the 0.7.0 and the step that 
you've done this time is really impressive.

Uhm... one more observation. On the info about the picture of Dynax 5D 
it is possible to have the AF point. I can't find it
on the makernotes, while it would be nice to be visualised on the 
picture as well (I suppose this can wait the
release 4.x.x :) )
