Like placing a sliding, variable-size bracket around a Photoshop
histogram,
If I were to set the darkest pixel in one of these images as
black, and the lightest as white, it would no longer look like frost,
but
some type of high contrast abstract painting...
Absolutely, I didn't mean to suggest that the bracket should always be
pinned to the edges of the histogram. I just meant it would be a useful
kind of feedback to have when you're setting exposure. Wouldn't that be
cool? You look though the lens and there's a little bar histogram with
say 64 steps that updates as you swing the lens around, and to the side
two tick marks indicating the brightest bright and the darkest dark
capable of being registered on your film or CCD, and the tick marks
shift as you change exposure time, f stop and film speed. It'd have to
be dependant on film stock too.
