PURPOSE: To obtain a photography in a simple way and just through a development process without having a reversing nor printing process, by using a photochromic glass in place of a negative film.

CONSTITUTION: A photochromic glass is put at the place where an objective lens focuses, and an image is formed on the photochromic glass to obtain a so-called colored negative. Then a lens is set to the negative to receive the image, and a film or paper which needs no negative nor the reversing process is put at the position where the image is formed. Thus the negative formed on the photochromic glass is photographed. It is required to produce the photochromic glass with a skillful control so that it is suitably applied to this invention. The existing multilayer color film is available to the above-mentioned film or paper. For instance, a reversal color film or a white/black negative film is available.
