Improvements in the methods for cinematographic projection, essentially characterized by the fact that the film has to project a focused and concentrated focusing system of the light beam of the projector, operatively arranged to cover the exact scope of the photogram to be projected without loss of light by illumination of areas adjacent to it, comprising as a film to project an embodiment whereby the frames of the same are governed by marginal holes, in arbitrary number, and depending on the width of the frame, which will always be illuminated with the maximum concentration of luminous framing, the film thus envisaging an embodiment for normal projection or an improvement for stereoscopic projection, which will be visible from a single film and a single projection apparatus by the viewer.
