Technirama is a screen process that was used by some film production houses as an alternative to CinemaScope. It was first used in 1957 but fell into disuse in the mid 1960s. The process was invented by Technicolor and is an anamorphic process with a screen ratio the same as revised CinemaScope (2.35:1). The Technirama camera used a film area twice that of the CinemaScope cameras, which created a sharper, less grainy picture. Cameras used 35-mm film, running it horizontally and utilizing an 8-perforation frame, double the normal size, exactly the same as VistaVision. VistaVision cameras were sometimes adapted. Technirama used a 1.5:1 anamorphic (squeeze) lens in order to take in a wider image. In the lab, the 8-perf horizontal negative would be "blown down" with a further 1.33 : 1 squeeze to create normal 4-perf normal (vertically running) prints with images having a squeeze ratio of 2:1, the same as CinemaScope. These prints could be shown with the same projection lenses as CinemaScope productions but would have greatly improved clarity owing to the double-sized original negative. Just as VistaVision had a few flagship engagements using 8-perf horizontal contact prints and special
