Color grading library and sample applications
On-device Core Image color-grading + film-look engine (Swift)
Waveform, vectorscope, histogram and picture assist in one FFGL effect for Resolume Arena and Avenue. It measures whatever's arriving at that point in the chain, and makes you say which matrix and range you're looking at rather than guessing.
REFgrade – colour grading by reference: transfer the look of a reference photo, then fine-tune with wheels, curves, HSL and scopes; export a 3D LUT (.cube). Krita plugin + standalone (prototype).
