Chroma Key Composition and
Settings
A key signal based on a particular color is used to cut out
the background, and the key fill is then inserted. The
inserted signal is also referred to as the foreground, and the
composite image is called a chroma key image.
In creating a chroma key image, either a normal mix or an
additive mix can be used.
Normal mix
The foreground is cut out with the key signal, and then
combined with the background, which has also been cut
out with the key signal.
Additive mix
The background, which has been cut out with the key
signal, is combined with the unshaped foreground. This is
effective for a natural-looking composite when the scene
includes glass or other translucent objects.
