At least for the WB though, what do you use? What the user has set? If
he intends to adjust it afterwards, his histogram may change. Don't
know about contrast though, maybe it doesn't have as much of a global
effect on the histogram as WB? With WB, some parts of the RGB space
will be weighted higher than others, i.e. R might have a slight
multiplier, while B might have a slight divider.

how the contrast setting(s) have anything to do with RAW
unless the histogram ISNT on the RAW data. RAW is RAW, NO?
contrast adjustments is post processing after RAW.

I'll bet that it's showing the histogram based on the (low-quality)
JPEG embedded in the RAW image (which I also believe to be used when
viewing zoomed-in portions of a RAW image on the camera review screen

JPEG).
Hi John,
Still pondering (still using Halfsize to generate mini-me pics from my
RAW DLs
too), I'll have to test your theory, sounds likely which means that the
in
camera settings will reflect the in-camera histogram for RAW image
capture. I
usually set my contrast to minimum so I guess that's why it's been a
little
less misleading than it appears to have been for others?
