What does 'tilt' refer to in camera operation?

Tilt in camera operation specifically refers to the movement of the camera in a vertical direction, which involves pointing the camera up or down. This action allows the operator to capture subjects that are higher or lower in relation to the camera's position. By tilting the camera, you can reveal different aspects of a scene or create dramatic effects by changing the viewer's perspective.

The other choices involve different camera movements or adjustments. Moving the camera left and right refers to panning, while scanning the horizontal set would also fall under panning as well. Adjusting the focus on the lens pertains to changing the clarity of the image rather than the angle of the shot. Understanding these distinctions helps in effectively utilizing camera movements to enhance storytelling in video production.
