Hi Bastien, once you have the range clamping in I'd like to go over a
final review, take time to understand the use case for some of the
settings, this wasn't clear to me without range clamping but I got the
impression some were redundant or gave very similar functionality but
I could be wrong.
Having a curve, a multiplier and clamp settings may not be needed -
the curve on its own should be enough?
