Clarence Sinclair Bull (May 22, 1896 – June 8, 1979) was an American portrait photographer who served as the head of the stills department at Metro-Goldwyn-Mayer (MGM) for nearly forty years. He is recognized as one of the definitive photographers of the "Golden Age of Hollywood," known for creating the high-glamour imagery that characterized the studio system's promotional efforts.
Born in Sun River, Montana, Bull initially pursued an interest in painting, studying under the Western artist Charles M. Russell. He moved to Hollywood in 1918 and began working as a freelance photographer. In 1924, upon the formation of Metro-Goldwyn-Mayer through the merger of several production companies, Bull was appointed to lead the studio’s photography department, a position he held until his retirement in 1961.
Bull is most frequently cited for his professional relationship with actress Greta Garbo. From 1926 until her retirement in 1941, Bull was Garbo's primary portrait photographer, capturing the vast majority of her official studio portraits. His work with Garbo is credited with helping to establish her public persona of mystery and elegance. Beyond Garbo, Bull photographed a significant portion of MGM’s roster of stars, including Clark Gable, Joan Crawford, Katharine Hepburn, Elizabeth Taylor, Vivian Leigh, and Grace Kelly.
Technically, Bull was a master of lighting and composition, often using dramatic shadows and precise highlights to idealize his subjects. His portraits were typically shot using large-format cameras, allowing for high levels of detail and extensive manual retouching of the negatives. This style contributed to the aesthetic standards of the era, where studio portraiture was used as a primary tool for star-building and film marketing.
Clarence Sinclair Bull died in Los Angeles, California, in 1979. His body of work remains a primary historical record of the actors and production styles of the mid-20th-century American film industry.
