Abstract: In a method of drying a photographic 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 processed 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.

Abstract: A method for processing a silver halide photographic material having at least one silver halide emulsion layer on at least one side of a support is disclosed. The method is characterized by pretreatment with a solution carried out prior to a development-processing. The solution being substantially unable to cause a development reaction though it contains a developing agent. The method improves the covering power of developed silver without deteriorating the physical properties of the silver halide photographic material.
