Who is responsible for both the camera department and grip department in film production?

The cinematographer, also known as the director of photography (DP), is responsible for overseeing the camera and lighting departments in film production. This role includes not only the selection of the camera equipment and the management of the camera crew but also collaboration with the grip department, which handles equipment that supports the camera setup, such as tripods, dollies, and rigs, as well as lighting control. The cinematographer's vision shapes the visual aesthetic of the film, and they work closely with both the camera and grip departments to achieve the intended look and feel.

The other roles mentioned have distinct responsibilities; for instance, the director focuses on the overall creative vision and directs the actors, while the producer manages the production aspects including budget and scheduling. The production designer is primarily responsible for the visual conception of the film's settings and props, ensuring that the environment aligns with the story's tone but does not oversee the camera or grip departments.
