With CS4 (or maybe CS5) they changed the generic "Brightness and

change was made in Lightroom. It pisses me off, actually, because I'd
quite like to have a real gamma slider in Lightroom...
It seems that there are two different UI philosophies. One, which I
could call the geek, or the Linux, philosophy lets you go in and
directly adjust the base values:
blacks would be the zero point of the conversion line
exposure would be the slope of the line
brightness would be the gamma
For me, in a perfect world, I'd be able to apply each of those to each
channel of the raw data for when I'm photographing in wonky light.
The other philosophy I could call the "don't bother me with details" or
the Mac philosophy, is for the people that don't want to worry about
what is going on under the hood, but want the computer to do all that
difficult thinking for them, and just give them what the computer thinks
is a perfect image.
It sounds like LR 4 is heading more towards the second philosophy. It's
frustrating because supplying the controls on the basic values would be
trivial. I may be forced to actually learn image manipulation
programming so that I can do those things before feeding my images to LR.
