Special effects photography in which a subject is photographed in front of a uniformly illuminated blue or green screen. During the effects process, the color screen is optically or electronically eliminated, and a new background is substituted in its place.

A process known from television and movie productions. Actors stand in front of a coloured wall, usually painted blue.

A green screen is also used more and more.
