Target specific areas using shape masks
A shape mask defines an area in the image so that you can apply color corrections either inside
or outside that area. For example, you might want to emphasize a subject’s face by darkening the
area around the face.
You can add multiple shape masks to define multiple areas, and you can also animate the shapes
so that they follow an area while a camera pans or an object moves as the clip plays.
