A cinematographer or director of photography (sometimes shortened to DP or DOP) is the chief over the camera crews working on a film, television production or other live action piece and is responsible for achieving artistic and technical decisions related to the image. The study and practice of this field is referred to as cinematography. Some filmmakers say that the cinematographer is just the chief over the camera and lighting, and the Director of Photography is the chief over all the photography components of film, including framing, costumes, makeup, and lighting, as well as the assistant of the post producer for color correction and grading.
