Technirama
Technirama is a film format that has been used by some production companies as an alternative to CinemaScope . It was first used in 1957, but abandoned in the mid-1960s. It was invented by Technicolor as an anamorphic format with the same aspect ratio as Cinemascope of 2.35: 1 (on the negative 2.25: 1).

Technirama used twice the film area compared to CinemaScope, which allowed a sharper and less grainy image. A 35 mm film was used horizontally with 8 perforations per image in the cameras, just like with VistaVision . For Technirama, anamorphic lenses were used in front of the lens by a factor of 1.5 to stretch the vertical image (in contrast to CinemaScope, in which the horizontal image is compressed). In order to achieve the required wider format, lenses with a shorter focal length had to be used.
