I personally mostly care about profiling for giclee reproduction work, which is 
why I've put so much effort into creating (not yet) perfect profiles.

However...I've also come to prefer such a profile as a starting point for both 
landscape and portraiture. And, indeed, my more recent work has generally been 
to come as close as I can to a colorimetrically-accurate rendering of the 
scene...which, obviously, means getting the light right in the scene itself 
(either by careful lighting in the studio or waiting for the Sun to do its 

And, of course, dynamic range outdoors becomes even more of a challenge with 
this approach, especially when one starts compositing multiple exposures. I had 
a huge challenge with that photographing the recent annular eclipse over the 
Grand Canyon...I went with a wide-angle (24mm tilt-shift) view with the ring of 
the Sun actually in the frame. I still need to do a lot of post-production on 
that one, but I've already got a first draft that's not all that far off from 
what I actually saw. And, yes, that includes detail in both the ring of the Sun 
and the shadowed parts of the Canyon....

I have a strong hunch that it's possible to make (in the studio) photographs 
with as much ``punch'' as some of those over-the-top HDR renditions, but with a 
single exposure and a colorimetric profile and basically no post-production. 
I've got a bunch of other stuff to do in the studio before I get a chance to 
see if that's really the case, but it's a project I'm looking forward having 
some fun with.

But, of course, that's just my own taste, and possibly delusions as well. 
Doesn't mean I don't drool over Velvia, or that I don't get a kick out of Ansel 
Adams -- quite the contrary.
