Method for creating synthesized images using diazo color films

The diazo film method involves the preparation of color synthesized images by the ultraviolet exposure of the diazo film without the use of additive projectors. Its relative simplicity makes possible the production of synthesized images at all centers making use of multizonal aerial and space photographs and an arbitrary combination of images obtained in different spectral channels for the purpose of obtaining the desired synthesized images. Diazo material makes it possible to obtain copies with a greater contrast than on the original materials. The successive steps in the processing of diazo materials are discussed. As a result of forming of different combinations it is possible to obtain from several tens to more than a hundred different variants of sets for interpretation.
