Hi Elle,
You know I'm with you regarding giving users more control over how
operations are performed, but tossing buttons for toggling between
linear and perceptual everywhere in the UI is not a proper solution.
It would be extremely confusing, and people would start toggling them
randomly without knowing what exactly they are for, and only a few
people would benefit from it.
I think that allowing that would complicate the UI and the the tools
themselves, as all of them should have both paths available.
A better solution would probably have to wait until proper
no-destructive editing is finally implemented, and operations are
visualized as a stack/chain/whatever.
I mean, instead of putting toggles on EVERYTHING, why not adding a tool
that says "from this point, the following operation/s will be performed
in linear/perceptual gamma"?
People used to node-based UIs will understand exactly what I mean.
The difference would be that only users who need the toggle will add an
operation that makes the switch when it's required. The UI will remain
lean, without extra options that could potentially confuse less advanced
users.
