Cinematography is the art of photography and visual storytelling in a motion picture or television show. Cinematography comprises all on-screen visual elements, including lighting, framing, composition, camera motion, camera angles, film selection, lens choices, depth of field, zoom, focus, color, exposure, and filtration.
A cinematographer or director of photography (sometimes shortened to DP or DOP) is the person responsible for the photographing or recording of a film, television production, music video or other live action piece. The cinematographer is the chief of the camera and light crews working on such projects and would normally be responsible for making artistic and technical decisions related to the image and for selecting the camera, film stock, lenses, filters, etc. The study and practice of this field is referred to as cinematography.
