Anonymous posted a topic in DaVinci ResolveThere are a set of LUTs inside the Film Looks folder in DaVinci resolve. How should one go about using it in their color grading workflow? I generally use a Color Space Transform node to input gamma as Rec. 709 and out gamma as Cineon Film Log and then place the FPE LUT(This is done in the last 2 nodes). In nodes prior to the color space transform, I do LOG to Rec. 709 and secondary grading.
All the 2383 print film LUTs, I worked with, shift all the greenery towards yellow. But movies, where this print film was used, have green greenery. I tried to use and compared Davinci Resolve LUTs, Steve Shaw LUTs, ImpulZ LUTs and so on. So it seems like this is typical thing for 2383 colorimetry. Yes, you can say that LUTs can't be close to film and every time colors are different. But as far as I know, Kodak provided it's colorimetry to Steve Shaw (light illusion). So I think I can trust it's yellowish thing. I use macbeth colorchecker, set up an exposure, contrast as accurate as possible, adjust WB very accurately. Also I tried LogC gamma, tried cineon gamma, tried not to use wide gamut color spaces and used (as it's recommended) rec709 gamut with cineon gamma and so on. But I still get yellowish greenery. Also I tried to apply these LUTs to test pictures to see what's exactly going on and did a lot of other things. All these LUTs ACTUALLY shift greenery to yellow. I can fix the greenery quickly by using hue curve. But I guess this is not the correct way to get green greenery. I saw a lot of hollywood movies with 2383 print film, but most of them have usual green greenery. Is it a standard operation with 2383 print film to adjust greens using hue curve? Or may be there is some matrix I should apply before, or anything else? I'd like to know what is correct way of working with 2383 print film. I can fix it easily without any artifacts using, for example 3d lut creator and it's AB curves in YUV mode, but I want to know the correct way. I guess solution is simple and obvious. And I know that using LUTs for look purposes isn't what cool colorists do (actually they do), but this answer makes sense only if actual 2383 film print DOESN'T shift green to yellow. Otherwise I'm trying to solve the same thing, what happens with a real 2383 print film.
