THE LOEW STATE Universal-International screen installation near the final completion stages.

perfecting new methods of making and exhibiting pictures without rendering useless the industryis vast backlog of already completed films.

Because of the length of time required from the start of a picture until it is

ready for release, these films which already are completed, are the exhibitoris guarantee of being able to keep his theatre in operation during this period of technical changes.

Therefore, what was needed was a means of giving a Hnew look" to todayis standard films, while at the same time

getting ready for the improved films of tomorrow.

Universal feels that this goal has been achieved.

The U-l Screen

Universalls new wide screen is said to be an all-purpose screen adaptable to todayts standard pictures projected either in standard or large size, as well as new pictures filmed in either two or three dimensions especially for the new wide screen. In other words, this screen can take any picture having an aspect ratio up to two to one, including todayis standard 1:33 to 1:00.

In cooperation with the Research Council of the Motion Picture Producers Association, U-lis special photographic effects department some months ago launched into extensive research and experimentation having a two-fold aimlarger and sharper pictures without using more light, and if possible using less light in theatre projectors.

Tests Conducted

Employing a Gonio photometer for testing light reflection qualities and an Eastman neutral test card as a starting point, tests were carried on for many weeks. The Eastman neutral test card has a 90 per cent diffuse reflectance which is approximately the same reflective quality as that of todayls best theatre screens.

Using a great variety of materials and coatings, the experiments were carried on along strict mathematical lines, and followed formulas which already had been proven in light reHection tests.

After weeks of experimentation it was discovered that a larger and brighter picture could best be achieved by spray coating a textile surface with aluminum powder and giving the screen a moderate curvature. The head of the scenic department finally devised a sprayed surface which was far superior to any other Uel tested.

Chen it was decided to actually construct a full sized screen measuring 25 feet in height and 50 feet in width for the purpose of additional full scale experiments. Since the studio did not have a projection room large enough to accommodate a screen of this size, an entire sound stage was taken over for the project.

While the test screen measured 25 by 50 feet, it need not necessarily be this size. In fact, it can be of whatever size is most suitable to a particular theatre as long as the two to one ratio is maintained.

The screen, curved on a 90 foot radius, is made of a textile sprayed with the aluminum solution developed by U-I. It has a light magnifying factor of approximately four to one, as compared to present theatrical screens of less than one. In other words, the light transmitted to the screen by the projection machine is magnified approximately four times by the screen re-transmitting the light back to the viewing audience. The reason for this light magnifying power is that the coated surface of the screen reflects the light in direct 'ays rather than diffusing it as happens when the light strikes a white fabric. screen.
