Various types of counter models have been treated in the literature over the past twenty years. In all these models the counter mechanism involves a fixed or random dead time following a registered event. In this paper a different type of counter mechanism is introduced in which the occurrence of two or more input events within a relatively short time is required to produce a registered (output) event. This model of an “R-fold coincidence counter” is applied to the development of grains in a photographic emulsion for both low-intensity and high-intensity reciprocity failure.
