METHODS OF SECURING A LARGE SCREEN PICTURE
OPEN DISCUSSION AT THE OCTOBER, 1930, MEETING AT NEW YORK,
N. Y.
PRESIDENT CRABTREE: In order to give everyone an opportunity to air his views on the possible methods of securing a large screen picture, we reserved a place on this program for an open discussion on the subject. As Professor Hardy pointed out, if the photographic emulsion were absolutely grainless, if it were sufficiently fast, if it were so hard that it could not be scratched, and that it would not accumulate dirt, then wide film would not be necessary. Enough light could then pass through the film to ensure a reasonably large screen picture.
It has been suggested that the 35 mm. film should be run sideways. I think Mr Fear was originally responsible for that suggestion. Please correct me if I am wrong.
MR. FEAR: I believe I was the first.
PRESIDENT CRABTREE: The wide image has been squeezed optically on the 35 mm. film and then stretched out optically in projection. You can see an example of that at the Capitol Theater this week. This picture was produced by reducing an image on 70 mm. film down to 35 mm. film. It has been suggested that the sound be put on a separate film so as to permit of more picture space on the 35 mm. film, and there is the suggestion of the Standards Committee to introduce a film intermediate in size between 70 mm. and 35 mm. There are probably other alternatives. I should like to have your opinions.
MR. STERN: I gave a demonstration at the Paramount Theater on the 30th of September in which standard 35 mm. film was projected with the theater's own Magnoscope projector on the large screen measuring 43 X 31V2 ft. with excellent definition, and without excess granulation. This result was made possible by a special laboratory process of my own which will make feasible the use of large screens with 35 mm. film. I have also an invention for putting the sound track on separate film, saving the whole field for the picture. This 80
