The Filmic ocio by @Troy_James_Sobotka has a false color view transform which seemed pretty useful. What would be needed to use this in ACES?
I believe Filmic is in sRGB/Rec709 linear working space, and the false color LMT uses FilmicLogEncoding as it processing space. What would be the correct way to use that LUT in an ACES config?
As it happens, I have just recently been experimenting with a false colour gizmo, with customisable colours and ranges (in stops). The current version uses the ordinary Nuke Colorspace node, which doesn’t include ACEScg. But I was thinking about changing the way it works so it just has a dropdown of common encoding combinations. I am happy to share it when it is done, if that would be useful to you.
