ACES in Photoshop - a tiny bit easier.

[piotrus3333]

Two luts in one (workflow with two .csp luts from fnord's Photoshop OCIO plugin). Small quality of life improvement:

Really cool!

Thank you, I will test and report back

mP_fnord_ACEScg2linsRGB seems to work as expected! I'm using the 2.0 config in the VFB as well.

Please be mindful this lut is for outdated ACES 1.2 version.

You're correct. I didn't look closely enough and my shot is pretty dark which hides the difference a bit. I'm on 2.0 as it ships with my 3D app(I'm on cinema) and looks like Max is the same, I'm sure Maya has 2.0 in its resources folder. Is the main issue with 2.0 that the fnord doesn't give accurate result even if you pick 2.0 for the conversion source and have the right transfers? Apologies if I'm coming out of nowhere with this but I'm really stumped on how to convert in photoshop and I was hoping there would be a workable solution by now. Thanks in advance for any help.

are you talking about ACES 2.0 or OCIO 2.0 support?

If fnord's PS plugin still does not work correctly with 2.0+ configs than you need at two luts to make ACES 1.3+ with Reference Gamut Compression setup. First csp lut 1D+3D to get to some log encoding with aces gamut compression (but not acescc or acescct as these go above 1.0 float) and than 3D lut to put that on display of your choice.

this is ACES 1.3 Reference Gamut Compression baked to an ARRI AWG4 LogC4 lut. Considering official recommendations from ACES people this would be the correct implementation of ACES 1.3 RGC via lut.

One lut might be enough:

photoshop_csp_lut.jpg - aces 1.3 with gamut compression, view transform srgb display.

edit: this example is done with csp lut with 1024 points shaper. you can use 4096 point shapers in csp luts in photoshop - it’s pretty much ocio quality transform.
