DaVinci Wide Gamut versions of the Film Look Luts.

I would love to see DaVinci Wide Gamut versions of the Kodak 2383 & the Fujifilm 3513DI LUTs come included with Resolve. Yes, Rec709 and P3 versions are there, but with the advent of HDR, I feel accurate versions of each need to be added for maximum flexibility.

That would be nice yes.

For 2383 there are plenty alternatives available though. For example these are free:
https://juanmelara.com.au/products/koda ... powergrade (can't remember if it was scene-referred)
https://go.jvke.us/2383 (DWG/LogC/ACEScct)

Cullen Kelly also has one but I can't find the link atm.

I like this idea.

there is no such thing of "hdr film lut" it is always an adaptation of and existing one.

True, but we could say the same about the SDR versions in that regard no? ;) The ones that come with Resolve are by no means the 'true technical' versions of it.

HDR film LUT would be the one that adds picture rendering in the style of some film stock but does not place ther result in some final display referred state but keeps it in an intermediate, so any output transform can be added on top of it. Kind of like RRT in ACES. There is a problem with this though: in color-managed project, CM systems own picture rendering is also applied, so things get screwed up.

Is it though? I often use looks designed for ACES but in DaVinci or ALF-2 DRT depending on which I like for the project and vice versa. If BMD would create a scene-referred FPE of Kodak and Fuji for DWG based on rendering through DaVinciDRT it wouldn't be that weird to use with other renderings especially given the look is stylized rather than 'technical'.

Maybe it works, but it is a double-applied look nevertheless. Depends on the goal I guess, any look is subjective anyway. But if goal is a a technical stock emulation lut, this is something that is quantifiable. And in that case applying look rendering on top is counter-productive. Counteracting lets say DRT mechanics in it could work but makes it not very clean logic wise.

The technique is similar to build a film lut inside aces
Start from acescct
Transform to cineon
Apply film lut (you get 709)
Aces inverse odt from 709 to acescct

Make a lut of that

And you have a acescct to acescct lmt that looks like film

Probably you can do the same in DWG

Btw, that technique has a nickname:

FACES (Fake-aces)....

I never said there was a such thing. I specifically asked for a DWG version.

Yes, I can do a color space transform, I was thinking about when I was new to Resolve and had no clue of how to do a proper transform.

The request isn't so much for me, it's more so that the default color space in Resolve is DWG, and it would help others.
