lay for a screen, a new lens, and an altered aperture plate in the projector.

The shape of this screen and its surroundings are important in giving a panoramic and wide screen effect in theatres. It is important that every detail of construction is closely adhered to if theatres are to obtain the maximum effect on audiences which Paramount feels has been found possible.


The Paramount panoramic screen offers several improvements in picture presentation. It is larger than the screen normally used, and wider with respect to its height. The illusion of a curved front

and appearance to the theatre is enhanced by curving the screen itself, and framing it with surrounds or wings that are also curved. The screen may be metallic finish so that the same screen can be used for the playing of both 3-D and 2-D pictures. It is strongly recommended that adequate light be made available so that a clear, bright picture will be presented to the audience.

Surround and Curvature

The surround portion of the screen closely resembles the design of Schlanger and Hoffberg, theatre architects and engineers of New York, which is incorpo THE PANORAMIC SCREEN AND SURROUNDS are

rated in the Synchro-Screen distributed by RCA. Surrounds of different shapes are also being produced and distributed by other theatre suppliers.

The radius of the screen illustrated in this article is shown as 90 feet, which would apply to a house with a proiection throw of about 120 feet. This curvature will vary somewhat, depending upon the width of the house and the projection throw. For normal houses, the radius of curvature should be equal to, or greater than three-quarters of the dis tance from the center of the screen to the projector, assuming that the projector is not further forward than the last row of seats. In very wide houses, the radius should be approximately equal to the projector throw.

For a given radius of curvature of the screen, the depth of the curVe increases as the screen is made wider. It is also true that for a given width of screen, the depth becomes less as the radius increases. If the width of the screen is fixed, ratios such as 1:75 and 1:85 can be shown with the same lens used for the 1:66 ratio, by simply exchanging the aperture plate in the projector. if the full height of the screen is to be used, however, with the 1:75 or 1:85 ratio, the side masking must be moved out to allow for a longer picture, the lens changed to one of shorter focal length, and the aperture plate also changed.

Dimensions With respect to the cornice, base, and wings, Paramount recommends retainr

ing the same cross-sectional dimensions for all screen sizes. In these cases the cornice, base and wings will be made longer or shorter as required to meet the new screen dimensions.

In all installations the wings should retain approximately the same angle with respect to a straight line drawn across the front of the screen.

The cornice, base, and wings are in effect a picture frame that is made larger or smaller to meet the size of the picture.

The following table lists picture heights for different picture widths. It may be necessary to vary the picture size from these specified dimensions in order to comply with available lens sizes.

The actual screen sheet size, including grommets and binding, will, of course, be about two feet greater in each direction. If additional width is to be allowed for other forms of presentation, the screen width and frame should be correspondingly increased.
