The Brightness function is responsible for correction of the semitransparent areas (like a correction of hair tips that should be darkened/brightened), affecting the image’s natural effect.

The Shrink function is responsible for reducing the object’s contour by softening it.

This is especially important for certain types of cameras, image from which can produce a white line around the object. It is possible to remove it with the Shrink function. You can also use it in the cases where keying is difficult in some places, due to the properties of the object’s edges or lighting. Be careful
not to trim the edges of the object too much, so that it doesn’t look unnatural.
