In contrast, if the full frame is filled during filming and the projectionist is relied upon to matte out the top and bottom in the theater, it is referred to as a "'soft matte "', as the aperture plate is not on the focal plane and causes a soft edge.

A 2 deg . magnesium fluoride ( MgF 2 ) objective prism mounted forward of the aperture plate is used to disperse the converging beam from the telescope : with the 1216 ?image focused onto the primary aperture, other wavelengths are excluded from the spectrograph producing a very low level of scattered light on the detector.

All professional cameras are capable of shooting 2.55 : 1 ( special'Scope aperture plate ) or 2.66 : 1 ( standard " Full " / " Silent " aperture plate, preferred by many producers and all optical houses ), and 2.35 : 1 or 2.39 : 1 or 2.40 : 1 is simply a hard-matted version of the others.

In April 1953, a technique simply now known as " wide-screen " appeared and was soon adopted as a standard by all " flat " film productions in the US . In this process, a fully exposed 1.37 : 1 Academy ratio-area is cropped in the projector to a wide-screen aspect ratio by the use of an aperture plate, also known as a soft matte.

Since 80 % of downtown theaters and 69 % of neighborhood theaters had already converted to widescreen by the end of 1953, and since theaters that made the transition would not have had the Academy ratio aperture plates anymore, it is very likely that many people saw the film in a matted widescreen ratio such as 1.85 : 1, which had become the non-anamorphic industry standard by September 1956.
