Methods of Securing a Large Screen Picture: Open Discussion at the December, 1930, Meeting of the New York Section

Mr. La Porte: During the past ten months we have been engaged in the development of apparatus for taking, processing, and exhibiting of pictures. We have used up to this time the 65 mm. width, not because that width is the only width, nor that we should not consider changing it, but for reasons which are of particularinterest. We had previously worked with a width of 56 mm. That width was chosen on the basis of the present 35 mm. height using standard perforations and doubling the width in order to make the width-to-height ratio equal to two to one.
