A cinematographer or director of photography (sometimes shortened to DP or DOP) is the chief over the camera and light crews working on a film, television production or other live action piece and is responsible for making artistic and technical decisions related to the image. The study and practice of this field is referred to as cinematography.
The cinematographer selects the camera, film stock, lenses, filters, etc., to realize the scene in accordance with the intentions of the director. Relations between the cinematographer and director vary; in some instances, the director will allow the cinematographer complete independence; in others, the director allows little to none, even going so far as to specify exact camera placement and lens selection. Such a level of involvement is not common once the director and cinematographer have become comfortable with each other; the director will typically convey to the cinematographer what is wanted from a scene visually and allow the cinematographer latitude in achieving that effect.
Several American cinematographers have become directors, including Reed Morano who lensed Frozen River and Beyonce's Lemonade before winning an Emmy for directing The Handmaid's Tale. Barry Sonnenfeld, originally the Coen brothers' DP; Jan de Bont, cinematographer on films such as Die Hard and Basic Instinct, directed Speed and Twister. Nicolas Roeg, cinematographer on films such as The Caretaker (1963) and The Masque of the Red Death (1964), directed Don't Look Now (1973) and The Man Who Fell to Earth (1976). Ellen Kuras, ASC photographed Eternal Sunshine of The Spotless Mind as well as a number of Spike Lee films such as Summer of Sam and He Got Game before directing episodes of Legion and Ozark. In 2014, Wally Pfister, cinematographer on Christopher Nolan's three Batman films, made his directorial debut with Transcendence; whilst British cinematographers Jack Cardiff and Freddie Francis regularly moved between the two positions.
In the infancy of motion pictures, the cinematographer was usually also the director and the person physically handling the camera. As the art form and technology evolved, a separation between director and camera operator emerged. With the advent of artificial lighting and faster (more light-sensitive) film stocks, in addition to technological advancements in optics, the technical aspects of cinematography necessitated a specialist in that area.
In 1919 Hollywood, the then-new motion picture capital of the world, one of the first (and still existing) trade societies was formed: the American Society of Cinematographers (ASC), which stood to recognize the cinematographer's contribution to the art and science of motion picture making. Similar trade associations have been established in other countries too. The ASC Vision Committee is known for working to encourage and support the advancement of underrepresented cinematographers, their crews and other filmmakers, and to inspire us all to enact positive changes through hiring talent that reflects society at large.
We call ourselves kinoks – as opposed to "cinematographers", a herd of junkmen doing rather well peddling their rags.
We see no connection between true kinochestvo and the cunning and calculation of the profiteers.
We consider the psychological Russo-German film-drama – weighed down with apparitions and childhood memories – an absurdity."
There are a number of national associations of cinematographers that represent members (irrespective of their official titles) and are dedicated to the advancement of cinematography. These include:
The A.S.C. defines cinematography as:
A creative and interpretive process that culminates in the authorship of an original work of art rather than the simple recording of a physical event. Cinematography is not a subcategory of photography. Rather, photography is but one craft that the cinematographer uses in addition to other physical, organizational, managerial, interpretive and image-manipulating techniques to effect one coherent process.
