CinemaScope was developed to use a separate film for sound (see Audio below), thus enabling the full silent 1.33:1 aperture to be available for the picture, with a 2:1 anamorphic squeeze applied that would allow an aspect ratio of 2.66:1. When, however, developers found that magnetic stripes could be added to the film to produce a composite ...
Projection dimensions are the width and height of the projector aperture plate, and by extension the film frame area which is projected. The aperture plate always very slightly crops the frame. Projection lenses indicates whether spherical (normal) or anamorphic lenses are used on the projector, and if anamorphic lenses, what anamorphic power ...
The basic 35 mm anamorphic format originally popularized as CinemaScope has been known by a number of other monikers. In some cases, these names actually refer to different lens designs and technologies implemented; however, the great majority are simply re-branded lenses originally known by another name.
Anamorphic 4-perf camera aperture is slightly larger than projection aperture. The initial SMPTE definition for anamorphic projection with an optical sound track down the side ANSI PH22.106-1957 was issued in December 1957. It standardized the projector aperture at 0.839 × 0.715 inches (21.31 × 18.16 mm), which gives an aspect ratio of c. 1. ...
Some studios sought to compensate for these effects by shooting color films with a full aperture gate (rather than the academy aperture) and then reducing the image in Technicolor's optical printer. This process is a predecessor of today's Super 35 format, which also uses a 1.85:1 ratio but one-third more frame area than does a standard 1.85:1 ...
The negative is shot exposing the Academy ratio using spherical lenses, but the top and bottom of the picture are hidden or masked off by a metal aperture plate, cut to specifications of the theater's screen, in the projector. Alternatively, a hard matte in the printing or shooting stages may be used to mask off those areas while filming for ...
A film format is a technical definition of a set of standard characteristics regarding image capture on photographic film for still images or film stock for filmmaking. It can also apply to projected film, either slides or movies. The primary characteristic of a film format is its size and shape.
Films released in CinemaScope, an anamorphic lens series used, from 1953-present, and less often later, for shooting widescreen films that, crucially, could be screened in theatres using existing equipment, albeit with a lens adapter.
