Green Screen Technology

Green Screen Technology is a form of Chroma key compositing (or simply Chroma keying), which is a special effects (SFX) composition of two of two or more images/videos that are edited together during the post-production process.  An object or actor(s) may stand in front of a green screen in order that the background may be edited.  Green screens are popularly used in news broadcasting (a weather host will always stand in front of a green screen), hosting shows, video games and motion pictures, like “Lord of the Rings.”
