Jack Asher B.S.C. (29 March 1916 – April 1991) was an English cinematographer. Having begun his cinematic career as a camera operator, he made his debut as a cinematographer, or 'lighting cameraman', on The Magic Bow (1946). He remains best remembered for his work with Hammer Film Productions, beginning with The Curse of Frankenstein (1957), the first of Hammer's Gothic horrors and the earliest colour version of the Frankenstein story. He was the director of photography on several of the colour Hammer films, including Dracula (1958), The Revenge of Frankenstein (1958), The Hound of the Baskervilles (1959), The Mummy (1959), The Two Faces of Dr. Jekyll (1960) and The Brides of Dracula (1960), as well as some of the company’s moody monochrome thrillers like The Camp on Blood Island and The Snorkel (both 1958).
