I would like to create a certain LUT for my game in Unity. The usual way would be to take a screenshot in your game, process this screenshot in an image editor like Photoshop / GIMP and then calculate the LUT from that.
I would like to re-create the LUT used in the movie Memories of Murder.
I do not have access to the un-processed film material, so I can not automatically create the LUT as I would normally do with the above approach.
The closest comparison between the original colors and the processed version that I could get were these images:
Is there any way to create a LUT from these 2 images somehow even if they don't show exactely the same moment?
