By using the video microscopy, the picture of the formation of anisotropy photoinduction in the form of grains in time is shown, when anisotropy in the film is induced in individual micrograins and the concentration and sizes of the grains are modulated depending on the light exposition. This phenomenon was observed in the gelatin film dyed with the mixture prepared with the saturated solutions of Chrysophenine and Acridine Yellow mixed with 1 : 1 proportion.
