RKO Radio Pictures released Danger Lights with Jean Arthur, Louis Wolheim, and Robert Armstrong on August 21, 1930 in a 65mm widescreen process known as NaturalVision, invented by film pioneer George K. Spoor. United Artists released The Bat Whispers directed by Roland West on November 13, 1930 in a 70mm widescreen process known as Magnafilm. Warner Brothers released Song of the Flame and Kismet (both 1930) in a widescreen process they called Vitascope. Metro-Goldwyn-Mayer, after experimenting with the system called Fanthom Screen for The Trail of '98 (1928), came out with a system called Realife in 1930. MGM filmed The Great Meadow (1930) in Realife—however, it's unclear if it was ever released in the widescreen process due to declining interest of the movie-going public.
By 1932, the Great Depression had forced studios to cut back on needless expense and it was not until 1953 that wider aspect ratios were again used in an attempt to stop the fall in attendance due, partially, to the emergence of television in the U.S. However, a few producers and directors, among them Alfred Hitchcock, have been reluctant to use the anamorphic widescreen size featured in such formats as Cinemascope. Hitchcock alternatively used VistaVision, a non-anamorphic widescreen process developed by Paramount Pictures and Technicolor which could be adjusted to present various flat aspect ratios.
Types
Masked (or flat). Introduced in April 1953. The negative is shot exposing the Academy Ratio using spherical lenses, but the top and bottom of the picture are hidden or masked off a metal aperture plate, cut to specifications of the theater's screen, in the projector. Alternatively, a hard matte in the printing or shooting stages may be used to mask off those areas while filming for composition purposes, but an aperture plate is still used to block off the appropriate areas in the theater. A detriment is that the film grain size is thus increased because only part of the image is being expanded to full height. Films are designed to be shown in cinemas in masked widescreen format but the full unmasked frame is sometimes used for television. In such an instance, a photographer will compose for widescreen, but "protect" the full image from things such as microphones and other filming equipment.
Super gauges The full negative frame, including the area traditionally reserved for the sound track, is filmed using a wider gate. The print is then shrunk and/or cropped in order to fit it back onto release prints. The aspect ratio for Super 35, for example, can be set to virtually any projection standard.
