Rawtherapee provides a RAW histo of sorts just before
demosaicing--takes RAW "WB" in I think and applies a "standard gamma"
so it says. Interesting, but a bit late by then. CHDK developers said
it is possible at least after the shot--but slow--they said "hardware
limited" but didn't go into details. The hack does provide RGB zebra
mode (I set for half press) and a clipped channel flashes in that color.
With the tiny sensor there is at best a half stop leeway. It is hard
to miss stuff flashing at you even in a hurray and that is good. I
vaguely remember Pentax having some type of Raw histo, but am not sure.
Limited unexpected clip, Mike
Oh, see some new Moose shots but quite late and time to get home and
will ck them later.
Yup, that's why I want the camera to give me much better advice on
ETTR.
Using the camera's histogram sometimes fools me and I end up
overexposing. Usually the raw file's headroom saves me... but not
always.
