Uniformity in Photographic Development

The difficulties encountered in achieving a uniform degree of development from point to point upon a photographic surface and the reasons therefor are discussed. Various methods tried in an effort to realize uniformity in the development of plates and cut film are described. Continuous wiping of the surface of the film being developed is necessary to remove emerging reaction products sufficiently rapidly, and recommendation is made of the use of a series of jets of developer to achieve this without damage to the emulsion surface.
