ColorVision's description of the Brightness slider in the Profiler RGB
documentation (PDF):

"Brightness - This adusts the brightness produced by the profile, similar to
how Photoghop's gamma adjustment in the Levels command works. It won't
suddenly blow your highlights out if you increase it, or suddenly block up
your shadows if you decrease [it]."
