Apply 3D Luts .cube files into an image using Python

Question

I'm searching for a way to do this, I have looked at OpenCV but at least I could find only ways to apply 1D Luts files with it (256 long). Does anyone knows how to apply 3D Luts (64x64x64) to an image using python? thanks.

Answer 1

This worked for me.

$ pip install pillow pillow-lut

And then using a random .cube file from an Adobe Photoshop installation:

from PIL import Image
from pillow_lut import load_cube_file

lut = load_cube_file("NightFromDay.CUBE")
im = Image.open("image.png")
im.filter(lut).save("image-with-lut-applied.png")
