AgX in Corona

[zhao liang]

Thank you for your answers!

More of AgX by Troy Sobotka - this time his Resolve version of it (quite different) married with a film look from Arri:

note: it does require a string option to turn off VFB's sRGB view lut so might be a bit more cumbersome to use.

But when importing exr's from corona to fusion, there is a extra gamma applied (1.2?) because the image in fusion is much darker than in VFB. And then you need to specify the float gamma thing to have the same result in vfb and fusion ?

AgX luts for Corona from this thread are made for default Corona behaviour regarding gamma transforms in VFB. by default VFB has hidden 2.2 transform after the TONE MAPPING stack and effects. it also has hidden gamma transforms in every LUT operator.
if you are using my AgX luts there is no need for string option changing VFB's gamma behaviour ("float gamma thing").

Wait, so for any LUTs from outside Corona install we need either the string option or a gamma operator @0.45 before the LUT? I remember trying some LUTs from other sources but gave up thinking they were not the right type.
