Camera movements like panning, tracking, dollying, tilting, elevating, and zooming in/out allow films to have variety by changing the camera's position and perspective. Panning involves turning the stationary camera left or right, tracking moves the camera along with a moving subject, and dollying smoothly moves the camera forward or backward on tracks. Tilting turns the stationary camera up or down, elevating raises or lowers the camera position using a crane, and zooming makes objects appear closer or further from the lens even when the camera is stationary. These techniques are used to follow subjects, reveal environments, convey emotions, and emphasize sizes and distances.
