What term describes movement in front of the camera, usually by the talent?

The correct choice to describe movement in front of the camera by the talent is "tracking." This term refers to following the subject as they move through the frame, which can create a more dynamic and engaging visual experience. In tracking shots, the camera typically moves alongside or behind the subject to maintain a specific composition or perspective, effectively showcasing the action or interaction with their environment.

The term "primary," on the other hand, generally refers to main subjects or elements in a composition rather than a type of camera movement. It does not specifically address the dynamics of motion in a scene.

The terms "pan" and "dolly" also represent various forms of camera movement but do not directly concern the movement of the talent in front of the camera. Panning involves swiveling the camera left or right, while dolly refers to the camera physically moving closer to or further away from the subject on a track. Understanding these distinctions is important for effectively utilizing camera techniques in visual storytelling.
