Innovative American cinematographer Ray Rennahan began his film career as a cameraman in 1917. He became one of the pioneers of color cinematography in the early '20s; during the '30s, he became one of the first to try the groundbreaking tri-color system from Technicolor. Among those early color experiments was the short La Cucaracha (1934). When not working as a director of photography, Rennahan worked as a color specialist on many prestigious films. For his work on Gone With the Wind (1939) and Blood and Sand (1941), he shared Academy Awards. Rennahan retired from cinema in the late '50s and began working in television.
