a'yup. I do think that the belief that each step of processing should make the
image look better prevents many folks
from getting better at post processing.

Simply lowering brightness works with some images, not so much with others. It
all depends on what you want to happen in
the shadows. I often decrease both brightness and contrast before LCE, to
control clipping both ends of the histogram.
The latter part should read "readjust with levels, curves AND/or brightness.",
as more than one is usually needed in my
experience.

You are correct, and whoever wrote such a thing is silly. You can smash an
image to bits that way. I occasionally use
Brightness to adjust a temporary layer so that Select=>Highlights or Shadows
grabs the range I want. The temp layer may
look terrible, but only exists, briefly, for selection purposes.
