Chroma Key Backdrops
Chroma Key Backdrops (also called "Green Screens" or "Blue Screens") are surfaces that are positioned behind
live actors and their props in a process that makes them appear to be at a location where they are not. The
screen can be green or blue or any color as long as this color is not part of the live action. The backdrop
is electronically replaced with another image or video in a process called compositing. This can be
done in real time or in post production.
