CinemaScope

CinemaScope commonly refers to widescreen processes or anamorphic techniques. These use different magnifications in the horizontal and the vertical to fill the screen. It is also the specific trademark name for 20th Century Fox’s commercially successful widescreen process. This uses an aspect ratio of 2.35:1 (originally it was as wide as 2:66:1) – to compete with Cinerama and 3-D processes in the 1950s.
