Dimension 150
Dimension 150 was introduced in 1966 movie recording procedures for 70mm wide screen movies.
Background
Dimension 150 was an evolution of Todd - AO. As Cinerama after 1962 no more donors found to produce three-lane movies, you hit upon the idea of 70mm films on deep curved Cinerama screens perform. Todd - AO jumped on this train.
Richard Vetter and Carl Williams subsequently developed a lens for filming, with a performance on a deeply curved screen of 150 degrees was possible. Thus, there was a return to the original idea of Michael Todd, who already in Oklahoma! and in 80 days went around the world in this direction. At that time, however, only a viewing angle of 128 degrees was possible.
Despite impressive images, the system did not prevail, since only a few cinemas prepares an remodeling on D-150. In addition, it was difficult for the directors to work with this extreme focal length. Just two movies were filmed in this format. 20th Century Fox applied the system first with D-150 and finally with dimension 150
