Effect
Color Grading
Apply lift, gamma and gain style colour grading across tonal ranges.
Lift, gamma and gain come from video colour correction, where each control shapes a different tonal band. Cinema finishing still speaks this dialect even when the software is new.
Treating colour as three tonal ranges keeps grades readable. You can warm faces in the mids while holding highlight colour separately.
