Virtual Cinematography: Relighting through Computation

Recording how scenes transform incident illumination into radiant light is an active topic in computational photography. Such techniques are making it possible to create virtual images of a person or place from new viewpoints and in any form of illumination. Some of the most interesting virtual relighting applications are in the area of filmmaking. A small crew could capture a real-world location to use it as a virtual film set, and the production´s cinematographer could light the set virtually. Then, actors filmed in a studio could he composited into the virtual set, their lighting being virtually created to make them appear to reflect the light of the environment and further shaped by the cinematographer for dramatic effect
