Luminance Math / luminanceMath Choice Rec. 709
Formula used to compute luminance from RGB values (used for saturation adjustments).
Rec. 709: Use Rec. 709 (0.2126r + 0.7152g + 0.0722b).
Rec. 2020: Use Rec. 2020 (0.2627r + 0.6780g + 0.0593b).
ACES AP0: Use ACES AP0 (0.3439664498r + 0.7281660966g + -0.0721325464b).
ACES AP1: Use ACES AP1 (0.2722287168r + 0.6740817658g + 0.0536895174b).
CCIR 601: Use CCIR 601 (0.2989r + 0.5866g + 0.1145b).
Average: Use average of r, g, b.
Max: Use max or r, g, b.
Clamp Black / clampBlack Boolean On All colors below 0 on output are set to 0.
Clamp White / clampWhite Boolean Off All colors above 1 on output are set to 1.
(Un)premult / premult Boolean Off Divide the image by the alpha channel before processing, and re-multiply it afterwards. Use if the input images are premultiplied.
Invert Mask / maskInvert Boolean Off When checked, the effect is fully applied where the mask is 0.
Mix / mix Double 1 Mix factor between the original and the transformed image.
