Disclosed is a method of processing a light-sensitive silver halide color photographic material comprising; subjecting to exposure a light-sensitive silver halide color photographic material comprising a support; a light-sensitive silver halide emulsion layer containing at least one of a core/shell silver halide grain containing 3.0 mole % or more of silver iodide and a tabular silver halide grain containing 3.0 mole % or more of silver iodide; and a compound capable of releasing at a developing processing a restrainer or restrainer precursor which forms silver salt having the solubility product with a silver ion, of 1.times.10.sup.-9 or less, and thereafter; carrying out a color developing processing by using a color developing solution containing an aromatic primary amine type color developing agent, for a period of 120 seconds or less and so as to have a value of (developed silver amount at the maximum density portion)/(total silver amount), of 0.5 or less. The method of processing a light-sensitive silver halide color photographic material according to this invention can accomplish improvements of graininess and sharpness, and also prevention of surface-peeling of the light-sensitive silver halide color photographic material and scratch of an emulsion surface during the processing.

Method of processing light-sensitive silver halide color photographic

A method of treating a waste solution resulting from the processing of a photographic material with a working solution is disclosed, wherein at least part of said waste solution is absorbed by a resin capable of absorbing at least 50 times its own weight of a liquid.

Method of treating photographic waste

An apparatus for treating a waste solution generated when a photosensitive material is processed by an automatic developing machine includes a waste solution reservoir which is maintained at a constant level. A drum, partially immersed in the waste solution, is rotated to coat its surface. The drum is heated to produce a waste vapor. The waste vapor is condensed by a condenser and filtered and solid wastes are scraped from the surface of the drum. The condenser has a drain tank for collecting condensate and a non-condensable gas component. The interior of the drain tank is sealed to form an air tight seal and has a vent for exhausting the non-condensable gas component from the interior portion to the outside. The air vent includes an absorption tower to treat the non-condensable gas component.

Waste solution treatment method and apparatus therefor

The present invention provides a container for containing a photographic processing solution which comprises a housing member and a partion member, thereby the container is divided into two chambers of which the first chamber is prepared for containing the photogaphic processing solution and the second chamber is prepared for collecting the waste solution. One part of the housing member forming the first chamber comprises a oxygen shelter for restraining oxygen permiation therethrough into the first chamber below 20 ml/m.sup.2 /24 hrs. The second chamber has a solution-absorbing material therein for facilitating the collection of the waste solution.

Housing pack for photographic processing solution

The main object of the invention is to provide a disk film developing apparatus which has a developing process section of non-light shielding construction having substantially no darkroom section and in which one or more disk films are developed while being accomodated in a cartridge. The photographic processing apparatus for the disk film according to the invention comprises a means for holding the cartridge containing the disk film therein, a means for supplying a processing solution into the cartridge, and a means for releasing the disk film from the cartridge. And, during the photographic processing, the disk film being contained in the cartridge can be rotated by a rotating means.
