Color keying, also known as chroma keying, lets you shoot a foreground scene and insert it into virtually any background; this can save you money and allow you to create shots that are impossible or highly dangerous to take as a single shot. For it to be effective, the key is in the details. In this course, Mark Christiansen shows how to produce feature-film-quality keys in After Effects that fit well within their new scenes, while retaining the subtle details—be they strands of hair or soft or translucent edges—that make the results believable.
