ABSTRACT:
In a method of drying a photoraphic light-sensitive material by use of drying air, the amount of light-sensitive material which can be processed within a predetermined time at a set temperature of the drying air is compared with the totalized amount of the light-sensitive material to be actually processed within the predetermined time, and, on the basis of the result of this comparison, the set temperature of the drying air can be adjusted. An apparatus for drying photographic light-sensitive material by use of drying air is arranged so that the amount of light-sensitive material to be actually processsed within a predetermined time, is detected by a detecting sensor and the thus-detected amount is compared with the amount of light-sensitive material which can be dried. If the amount of light-sensitive material to be actually processed exceeds the amount of light-sensitive material which can be processed, such a display is conducted that the apparatus is not ready for insertion of further light-sensitive material. Accordingly, the light-sensitive material can consistently be dried at a proper drying temperature.
