Concept
Anamorphic format
Summary
Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native . It also refers to the projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen (not to be confused with anamorphic widescreen, a different video encoding concept that uses similar principles but different means). The word anamorphic and its derivatives stem from the Greek anamorphoo ("to transform", or more precisely "to re-form"), compound of morphé ("form, shape") with the prefix aná ("back, again"). In the late 1990s and 2000s, anamorphic lost popularity in comparison to "flat" (or "spherical") formats such as Super 35 with the advent of digital intermediates; however, in the years since digital cinema cameras and projectors have become commonplace, anamorphic has experienced a considerable resurgence of popularity, due in large part to the higher base ISO sensitivity of digital sensors, which facilitates shooting at smaller apertures.
The process of anamorphosing optics was developed by Henri Chrétien during World War I to provide a wide angle viewer for military tanks. The optical process was called Hypergonar by Chrétien and was capable of showing a field of view of 180 degrees. After the war, the technology was first used in a cinematic context in the short film To Build a Fire (based on the 1908 Jack London story of the same name) in 1927 by Claude Autant-Lara.
In the 1920s, phonograph and motion picture pioneer Leon F. Douglass also created special effects and anamorphic widescreen motion picture cameras. However, how this relates to the earlier French invention, and later development, is unclear.
Anamorphic widescreen was not used again for cinematography until 1952 when Twentieth Century-Fox bought the rights to the technique to create its CinemaScope widescreen technique.
