ABSTRACT:
In an automatic developing machine in which a photographic film is dried by a drying unit after development, a method of controlling the temperature and/or humidity of the film drying air in order to prevent variation in the film size before and after the processes of development and drying, which comprises prior computation of the variations in the film size according to a temperature and humidity of outside air, thereby determining the optimum operating condition of the drying unit from a result of the prior computation, and thereafter setting the drying unit with the optimum operating condition so that the automatic developing machine may process the film without variation in the film size.
