Example 2
There are times when we want to remove the area inside the garbage mask and keep the area
outside the holdout mask from being keyed. In these cases, the Invert option must be enabled to
reverse the order for both masks.
In the foreground shown below, the ceiling lamp (1) can be removed by a reversed garbage mask
and the green screen (2) can be chromakeyed with a reversed holdout mask. After a chromakey is
applied to the foreground, the background should show through the green screen only.

First enable garbage and holdout masks and turn ON Invert for both masks. Then adjust edges of
the two masks accordingly. As shown in the diagram below, the garbage mask is depicted by
rectangle 1 and the holdout mask is depicted by rectangle 2. See
Sections 5.1
and
5.2
for
instructions on how you can activate the two masks on the foreground.
