Abstract
Low-intensity reciprocity-law failure in photographic exposure represents an inefficiency arising from the regression of the latent image in its early stages of growth. Evidence has been given to show that the stable sublatent image requires for its formation the action of two or more quanta in a small critical time period, τ. A new method for evaluating this critical time period by intermittent exposures is described.Keywords
