Chapter 5 Basic Operations — KEY
[Matte Sponge] makes the semi-transparent parts non-transparent, but does not change the color to the original color. (When the operation of [Clean FG
Noise] is performed, the image returns to the original state including color information.)
r
[Make FG Trans]
Increase transparency of the low transparency area in the foreground image.
This is useful when making areas covered with thick smoke or clouds in the foreground image semi-transparent.
r
[Restore Detail]
Decrease transparency of the high transparency area in the background image.
This is useful when restoring the details of an image (such as stray hairs or smoke), which have been lost as a result of operations such as [Clean BG
Noise].
r
