MGM Camera 65
Camera 65 was introduced in 1957 movie recording procedures for 70mm wide screen movies.
Background
The development of the Camera 65 was strongly along with the selection of an appropriate admission process for which exploiting dividend in preparation MGM - scale production Ben Hur. The then newly introduced formats still showed some weaknesses. With the 35mm Cinemascope by 20th Century Fox any undistorted close-ups were possible, and from the film negative of brought out by Michael Todd 70mm Todd - AO 35mm film prints could not be drawn. Therefore, with Panavision to develop their own high-definition format, which should eliminate these disadvantages MGM decided.
Old Mitchell cameras from the 1930s were converted to 65mm film and equipped with a newly developed anamorphic lens from Panavision, which squeezed the image in a 1.25 factor and recorded with a frame rate of 24 frames per second. From the film negative, a 70 - mm screening could now be created with six Magnettonstreifen or a 35mm normal film copy. In both versions of the film for the demonstration had to be equalized. The lower image compression distortions in close-ups could be prevented. The copying to the smaller 35mm format increased image quality. The 2.76:1 aspect ratio was possible with a 70mm performance was not always due to limited screen width but possible. Even when copying to the 35mm film were lost on both edges of image information. The director and the cameraman had this image losses in both Aufführversionen considered during the shooting. Panavision wanted to give the format of the name Ultra Panavision, MGM but prevailed with Camera 65.
The first film in this format was the country of the rain tree, but was only listed on 35mm film. It was not until Ben Hur was sold as 70mm film. During the production of Mutiny on the Bounty Panavision took over the process since MGM got into financial difficulties due to the cost. This film marked the transition from Camera 65 on Ultra Panavision and also the future use by other film companies.
