The American Society of Cinematographers was founded in Hollywood in 1919 with the dual purpose of advancing the art and science of cinematography and bringing cinematographers together to exchange ideas, discuss techniques and promote the motion picture as an art form—a mission that continues today. Neither a labor union nor a guild, the ASC is an educational, cultural, and professional organization. Membership is by invitation only, extended to directors of photography who have demonstrated outstanding ability with distinguished credits in the industry and good personal character. The ASC is the publisher of the award-winning, international publication, American Cinematographer.
