The concept behind using a green screen allows film professionals to add visual effects not typically possible in a live shoot. This technique allows the compositing of two images or frames together where a specific color or a small color range gets replaced by other visual element/s. The process called compositing is widely used in animation work wherein various visual elements making up a scene get combined together into a single frame. In the case of such visual effects made for a production with live action elements shot in a green screen, it is more specifically referred to as chroma key compositing or chroma keying.
