A movement of the fixed camera, in which the camera pivots vertically, from up to down or vice versa. Tilting a camera is a motion similar to that of someone nodding their head to indicate “yes”. See also panning.
Common functions of tilt shots are:
showing an object that extends above or below the frame (reveal)
introducing a location (up ► down)
evoking suspense by showing a subject from the feet to the head (down ► up)
concealing what is happening by tilting up to the sky (down ► up)
