What movement is used when you move the camera up or down to follow a subject vertically?

The correct answer is tilting, which refers to the camera movement that pivots the camera up or down from a fixed position. This technique allows the camera operator to adjust the vertical angle of the shot, effectively following a subject that is moving up or down. It is commonly used to capture action that occurs at different heights, such as a person climbing stairs or a bird taking flight.

Other terms are related but refer to different movements. Pedestaling typically involves raising or lowering the entire tripod with the camera mounted to it, changing the camera's height while keeping the angle the same, which could potentially follow a subject vertically but does not pivot in the same way as tilting. Trucking is a lateral movement where the camera moves side to side, while dolly in/out refers to moving the camera closer to or farther away from the subject along a linear path. While these other movements are important in filmmaking, they do not specifically describe the vertical motion indicated in the question.
