Mechanism of Selective Action of Developers on Photographic Layers: I. Mechanism of Catalytic Action of Centers of Development

Photographic development, from the technical side, is a unique process of very powerful intensification of the results of the primary action of radiant energy on photographic layers. An approximate computation¹ shows that the factor of this increase is of the order of 10¹⁰. Consequently, if development were not known, exposure or illumination during photography would have to be increased billions of times in comparison with present usage and under such conditions, clearly, photography and cinematography with their present brilliant achievements would be impracticable.
