Biography:

Alvin Wyckoff (July 3, 1877 – July 30, 1957) was an American cinematographer who worked on more than 80 films between 1914 and 1945. Several of Wyckoff's films had sequences filmed in the early Handschiegl Color Process, originally billed as the "DeMille-Wyckoff Process". Wyckoff also worked with DeMille to develop the Lasky-lighting technique, which made selective lighting possible. From Wikipedia, the free encyclopedia
