I believe that the histogram display data is extracted from the embedded JPG
file which is affected by camera settings. Until the histogram is a
function of
the RAW data the histogram or a clipping indicator is only going to be a
guide
not an absolute indicator.
Okay, but I've had the histogram fail to show clipping when shooting in
JPEG mode. If the histogram is based on JPEG mode, and the shooting mode is
JPEG mode, then an "ideal histogram" should always indicate the presence of
any clipping, shouldn't it?
take care,
