Originally, film was a strip of cellulose nitrate coated with black-and-white photographic emulsion. Early film pioneers, like D. W. Griffith, color tinted or toned portions of their movies for dramatic impact, and by 1920, 80 to 90 percent of all films were tinted. The first successful natural color process was Britain's Kinemacolor (1908–1914), a two-color additive process that used a rotating disk with red and green filters in front of the camera lens and the projector lens. But any process that photographed and projected the colors sequentially was subject to color "fringing" around moving objects, and a general color flickering.

The Frazier lens is a special camera lens designed by photographer Jim Frazier. The Frazier lens provides a massive depth of field, allowing the foreground and background of an image to be in focus. Frazier's lenses have been widely used in Hollywood and wildlife cinematography. In addition to its unique depth of field properties, the Frazier lens is significantly smaller than previous deep focus lenses allowing more versatility and flexibility to cinematographers. The main feature of the lens, an extended tube with a rotating prism, allows cinematographers to place the camera in a variety of positions for a given shot. Cinematographers then rotate the prism to correct the horizon. This feature allows directors and cameramen to achieve shots in minutes that previously took cinematographers hours in rigging and designing special sets to accommodate shooting positions.
