Technicolor Three-Strip Camera

The Technicolor Three-Strip Camera was a specialized 35mm motion picture camera manufactured by Mitchell Camera Corporation to Technicolor's specifications, with fewer than 35 units built between 1932 and 1954. It used a beam-splitting prism to expose three separate strips of black-and-white film simultaneously through red, green, and blue filtration, producing full-color images through a dye-transfer printing process. The system required significantly more light than standard photography, with an effective ASA of 5. Three-strip production ended in the mid-1950s when single-strip color negative film made the process obsolete.
