The camera operator is responsible for physically operating the camera and maintaining composition and camera angles throughout a given scene or shot. In narrative filmmaking, the camera operator will collaborate with the director, director of photography, actors and crew to make technical and creative decisions. In this setting, a camera operator is part of a film crew consisting of the director of photography and one or more camera assistants. so it's a very important job ! no operator would not be a good movie and we all just like perfect images in cinema.
