CINEMASCOPE INVENTOR Henri Chretien explains the process in Spyros Skouras, ZOIh-Fox president.

CinemaScope. Said to contain millions of tiny "lenses" renecting greater light, this is an all-purpose screen which may also be used for showing 3-D, standard 2-D, or any of the other wide angle lens projection methods. The Miracle Mirror screen may be had in any size that will maintain the CinemaScope aspect ratio of 2:55 to 1. The screen curves to a depth of five feeteenough to afford a feeling of engulfment without reiiecting annoying light from one curved end of the screen to the other.

Horizons are level, while the increased ratio of length to height of the screen permits scenery to be viewed more as the eye is adapted to see it-from side to side, not up and down. In this connection, it is recalled, motion pictures had to sacrifice some of their screenis Vital length when sound came, because one side of the picture frame was used to record the sound track.

Due to the immensity of the screen, few entire scenes can be taken in at a glance, enabling the spectator to View them as in life, or as one would 'atch a play when actors are working from opposite ends of the stage.


The following material which gives the background and details of the anamorphic lens, is from, rm addrch- by the inventor Henri Chroticn.


General Considerations The normal field of natural vision is

much more extended in width than in height; this follows because the visual field of the two eyes are co-extensive one with the other.

This is fortunately compatible with the most common aspect ratio of objects which we see; the enlarged scope of landscapes in a vertical direction is more rare, and the head movements in the


vertical direction are less spontaneous thanthe horizontal movements.

It is undoubtedly due to this phenomenon that there is an exaggeration of the apparent height of elevated monuments and which has led the builders of cathedrals to locate them on elevated places where precisely this lack of space to contemplate them still further increases the impression of elevation toward the sky. I think that it is an error of these modern times to free them from obstructions in order to permit distant views.

Ever since the beginning of motion pictures the aspect ratio of the screen has been a compromise between these two directions. For ordinary photography where one can, by convenient arrangement of the apparatus on its support, take pictures whether it be in height or in width, the manufacturers have been constrained to adopt as format for the plates a ratio which is unchanged when one cuts the plate in half.

Outside of these sizes photographers use longish formats which are taken from the preceding formats by means of cropping.

Panoramic Photography

Besides the aspect ratio framing the pictures there is still posed the question of field of view.

Many procedures have been used to extend without limitation the photographic field. Col. Moessard has imagined apparatus having spheroetoric objectives which image on a single horizontally arranged plate all the scope of the horizon, which cannot be done without yielding a considerable distortion. Other authors have conceived of the formation of an image on a film rolled in cylindrical form concentrically with the photographic objective, this latter being given a rotational movement around the exit nodal point.
