Bear in mind that the on camera histogram may be a little misleading - it is
usually the histogram as applied to a to a JPEG which has had the camera's
default conversions applied to it (including a fairly steep S curve)

So what you see there has already dumped a lot of the information that would
be in the RAW file - including highlight detail

Add in - that rather like the old days you still need to tweak the iso of a
digital camera (remember shooting slide film at 80 or 125 instead of 100?
etc or rating 160 neg film at 125 or 100?) . A digital camera's 100 iso may
actually be closer to 80 or 125 - you need to run your own tests - just like
the old days  :-)
