Matte painting is a traditional visual effects technique wherein a painted image is combined with film footage to alter, enhance or extend the set, without the cost and effort having to create a physical set. Unlike the travelling matte or back projection technique, where the action occurs in front of a large painted backdrop, matte paintings are applied to the footage after shooting, with the matte image superimposed over the background areas which need to be covered[1]. Traditionally, this was done using glass plates with the scenery painted on; these were placed between the camera and the film footage, and the resulting composite image rephotographed [2]. Currently, the use of physical paint has been superseded by digital images created using a tablet as a drawing device. Matte painting can also be used in combination with a computer-generated 3-D environment, allowing for 3-D camera movement [3].
