The camera angle, the level and height of the camera, is an important tool to express the mood or convey a character’s standing or situation.
How, how fast, and where the camera moves determines the angles and shots it will produce. Camerawork includes both the aforementioned framing and the movement of camera which creates the illusion of depth (film is a two-dimensional photographic medium).
Framing—the use of the camera’s viewfinder—is essential to the distinction between, and the fusion of, the offscreen space beyond what the camera can “see” and the scene on screen (what film audiences see). Shots, composition, and mise-en-scène are informed and dictated by the coexistence of on- and off-screen spaces.
For various purposes the cinematography may call attention to itself. Metacinema refers to films that allude to itself or to the cinematic conventions. It is a self-referential act. When cinematographic elements become noticeable, when characters break the fourth wall to address the film audiences, metacinema occurs.
