This week marks the 100th anniversary of the ASC (The American Society of Cinematographers). To celebrate the occasion, we present exclusive production stills from films shot by an ASC founding father, Arthur Edeson. Edeson, who originally began as a portrait photographer, went on to a pioneering career in Hollywood with credits including The Maltese Falcon (1941), Casablanca (1942), Frankenstein (1931), The Thief of Bagdad (1924), The Lost World (1925), and The Big Trail (1930). The gallery below showcases a sampling of the master at work (all photos courtesy of ASC).
