Oh, my bad! Sorry for not being more clear - I’m currently experimenting with Spectral Film Lut from Jan Lohse (GitHub - JanLohse/spectral_film_lut: Generate LUT for film emulation based on film datasheets.).
I don’t have any tutorial for it other than the readme on that Github!
Also, sorry in advance, I’ve tried to read a lot of this thread previously, but haven’t got through it all. So if it’s already been discussed, apologies!
Hope that helps and thanks!
