Abstract
Disclosed are method and device for automatically controlling the time period of photographic development for each specific combination of a photographic developer and a photosensitive material for the purpose of obtaining a substantially same or optimum photographic development result at various temperatures. Through utilization of the knowledge of a certain relation between the time period of photographic development and the temperature of the photographic developer which will produce a same photographic development result, the time period of photographic development is adjusted, for instance, by changing the speed of a conveyor carrying the photosensitive material through the photographic developer. The mentioned relationship may not be always expressed by a linear function with a desired accuracy but may be approximated with a desired accuracy by means of various mathematical functions such as polynomials and irrational functions.
