An image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.
Eighty percent of a picture is writing, the other twenty percent is the execution, such as having the camera on the right spot and being able to afford to have good actors in all parts.
Billy Wilder As quoted in The New Hollywood : American Movies in the '70s (1975) by Axel Madsen
