Chroma Key Operating Notes
3.
Adjust the secondary
Angle
so that changing secondary
Chroma
suppression moves the color in the desired direction. You are trying to
match the color of the translucent areas to an opaque (uncorrupted)
area of the foreground subject.
4.
Decrease secondary
Chroma
suppression for the best match between
corrupted (translucent) and uncorrupted (opaque) areas. Interaction
between secondary suppression Angle and Chroma suppression may
require repeating these adjustments.
5.
Increase secondary
Luma
suppression to balance lightness of the
translucent and opaque areas.
6.
Repeat secondary suppression Angle, Chroma suppression and Luma
suppression for best results.
