Combining Keys
and Using Mattes
A key is the actual image channel that’s generated by different secondary
operations to isolate specific portions of images to work on. This chapter
covers different ways you can manipulate and combine keys from multiple
nodes, or propagate keys among nodes. It also shows different ways you
can use mattes that are imported from other applications, as well as how
to use the Key palette to further manipulate keys in different ways.
