What does a tilt down (TD) movement do in cinematography?

A tilt down (TD) movement in cinematography refers specifically to the action of swiveling the camera downward. This technique allows filmmakers to shift the viewer's attention from a higher point to a lower point within a scene, helping to reveal important details or to establish context. By tilting down, the audience can be shown a character's actions, the environment, or objects that are positioned below the original camera angle. This movement can also convey a sense of descent, allowing for various creative storytelling opportunities within a visual narrative.
