happens to measured in stops. What I have considered in the past as the
definition of brightness has changed a bit. It really means detail or
tone and as far as I know it is fixed in a given scene. If you look in the
Gallery this week at Roger Eichhorn's Pit Stop you can see the problem as
the buildings in the background are bright white with out much tone/detail. Now
in a very high brightness scene one can make a two maybe three exposure at
varying levels and get all the detail the scene has to offer. This is what
the Photoshop CS2 can do. You make two exposures, one with a high exposure and
one with a low exposure and Photoshop combines into one printable file.But the
scene has to stand still while you do the two exposures. People and event s
don't stand still but landscape usually does.
I shoot only slides but I was considering shooting
color negatives if I can get the brightness range in the negative and then on to
the paper. I have a B&W negative I shot many years ago that has the
same problem as Roger picture. I think I have finally fiddle with it enough in
Photoshop 7.0 to where I filled in the blank white area so it doesn't look
fake or manipulated. If I have time this week end I try printing it to see what
it looks like in a print.

I don't think you can create tones/detail which are
not there. At least not with Photoshop 7.0 You can make something more contrasty
but you are just stretching out the tones you got.
