One image. If there's a cut, you've changed shots. Shots can range from split seconds, like in Terminator 2, to several minutes, such as in Secrets and Lies or the opening sequence of Halloween. Shots are generally chosen by the director although the writer can use capital letters to suggest where the camera should be. When a writer absolutely must have a certain shot at a certain moment in a film, he has a few options each described in detail elsewhere in this list: INSERT, ANGLE ON, and CLOSE ON.
