Tilting is a cinematographic technique in which the camera stays in a fixed position but rotates up/down in a vertical plane.
[2] In some situations the lens itself may be tilted with respect to the fixed camera body in order to generate greater depth of focus.
Attention might convey a potential love interest with "elevator eyes" or concern with sizing up an opponent.
Combining tilt with camera position could show a face planting or tipping over backwards.
[9] Extreme tilting would follow the subject past the zenith or nadir to a full 180 degrees, starting or ending with an inverted view of the world.
