'''Compositing''' is the process or technique of combining visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene. [[Live action|Live-action]] shooting for compositing is variously called "[[chroma key]]", "blue screen", "green screen" and other names. Today, most compositing is achieved through [[digital image]] manipulation. Pre-[[digital compositing]] techniques, however, go back as far as the trick films of [[Georges Méliès]] in the late 19th century, and some are still in use.
