Clayton,

You are right about the grain structure as far as emulation goes, but I am
specifically addressing the tonality issue, which I strongly disagree with
Truman's assessment.  I still see no reason why there is any problem at all
in the shoulder and/or toe.  So what if it's non-linear, it's still
deterministic and given that, still mappable.  I do it all the time, so do
you too, if you save tonal curve adjustment settings.
