◎ Radiance Grade Match New v2.1

RadianceGradeMatch

Shot-to-shot color matching using CIE L*a*b* mean and standard deviation transfer. Connect a source image and a reference image — the node matches the source's color statistics to the reference and outputs a matched image plus a grade_info JSON that can be replayed on other shots.

Inputs

Name	Type	Default
source	`IMAGE`	—
reference	`IMAGE`	—
match_strength	`FLOAT`	1.0

Outputs

Name	Type
IMAGE	`IMAGE`
