Denys Coop BSC (20 July 1920 – 16 August 1981) was a British cinematographer and camera operator. He served as the British Society of Cinematographers (BSC) president from 1973 to 1975.
Coop entered the film industry at the age of 16 as an apprentice to cinematographer Freddie Young at Elstree Studios. He subsequently worked at Pinewood and Denham Studios before serving in the Fleet Air Arm during the Second World War. He later transferred to the Army Kinematograph Service. Following the war, he returned to the industry at Shepperton Studios under contract to Alexander Korda and became a freelance camera operator in 1956.
As a camera operator, Coop worked on a number of notable British productions, including The Third Man (1949), The Fallen Idol (1948), The Sound Barrier (1952), Richard III (1955), The Prince and the Showgirl (1957), Bonjour Tristesse (1958), Our Man in Havana (1959), Sons and Lovers (1960), The Guns of Navarone (1961) and Lolita (1962).
Coop became a director of photography during the 1960s. His credits included A Kind of Loving (1962), This Sporting Life (1963), Billy Liar (1963), King and Country (1964), Bunny Lake Is Missing (1965), The Birthday Party (1968) and 10 Rillington Place (1971).
His cinematography on Billy Liar, King and Country and Bunny Lake Is Missing resulted in three consecutive BAFTA nominations for Best Cinematography in the black-and-white category.
Coop subsequently became involved in specialist photographic and visual-effects work. He was director of photography for the flying and process-photography work on Superman (1978). His work on the film contributed to the development of the photographic techniques used for its flying sequences. The BSC awarded him its Bert Easey Technical Award in 1978 for his work on the film.
For Superman, Coop shared a Special Achievement Academy Award for Visual Effects and subsequently received a BAFTA Michael Balcon Award for his contribution to the film's visual effects.
