Abstract
In a previous paper the writer attempted to show that the latent photographic image is formed in two distinct and separate steps. In the present paper this theory is compared with recent physical research. The writer concludes that each of the photographic steps consists of the attraction of one electropositive silver ion to a sensitizing speck on the grain surface which has previously captured an electron. The reciprocity law failure at high intensities is explained by the minimum time required for the attraction of a silver ion. The reciprocity law failure at low intensities, is explained by assuming that a sensitizing speck which has attracted only one silver, ion is unstable und that the number of grains activated by a single capture decreases exponentially with time. From these physical theories the whiter deduces mathematical relations governing the photographic characteristics. H&U curves and reciprocity failure curves computed front these relations are in good qualitative agreement with experimental curves. The assumption of an unstable intermediate state of insufficiently exposed grains implies certain effects of delayed fogRinx (and delayed development which are verified by experiments.
