| Abstract: |
A photographic objective, in whose plane a set of filter strips associated with different colors is located, forms an image on a black and white film while the lens elements of a lenticular grating form images of the set of colored strips on the corresponding areas of the film. All strip images together form a strip grating on the film so that the image formed by the objective can be reproduced as a color picture by the diffraction orders of the strip grating.

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended
1. A method of photographic color recording and reproduction, comprising the steps of forming by an objective a photographic object image on a photosensitive surface which is sensitive to white light; forming by a lenticular grating having a frequency of at least 60 lines per millimeter a plurality of color images of a set of differently colored filter strips located at least behind parts of the objective so that said strips absorb the respective color components of light and strip grating composed of the images of said strips is recorded on said photosensitive surface and is overlapped by the object image on said surface; developing said photosensitive surface; and reproducing said object image on the developed photosensitive surface as a color picture by the diffraction orders of said strip grating.
