PROCEDURE for the film printing and projection, and apparatus for, practice of the procedure laid down

摘要

The method of cinematographic projection and printing uses normal type films. The method consists of exposing the film by contact or optical means. This produces a first series of odd photographs orientated in the same sense. These photographs being spaced from each other by a distance equal to the length of the photograph. In these spaces a series of equal photographs is developed. These photographs are arranged in the same way but are in reversed order with repeat to the odd photographs. On the finished film are two wound tracks, one for the odd series of photographs the other for the even series.
