Lut file format #148
Description
Image is really the high level tool of image manipulation, It has a most integrated workflow.
I see that all the logic for LUT is already integrated.
In the industry there are precise standards to express and port LUT
.look
.vtl (panasonic)
.cube
DaVinci Resolve, Affinity, Lightroom profils export, ... all support it.
Nx and programming methods are precise but not up to task when esthetic prime.
For your consideration and feedback please ;)
