摘要： PURPOSE: Black-and-white photographic silver halide elements containing small amount of silver, such as radiographic films, can be processed quickly using black-and-white developing and fixing compositions having reduced photoprocessing activity. CONSTITUTION: The entire process is fairly rapid and effective despite the lowered concentrations of photographic developing and fixing agents. A black-and-white developing composition has a pH of from about 9 to about 12. A fixing composition has a pH of from about 4 to about 6 and comprises from about 250 to about 950 mmol/l of a photographic fixing agent containing a sulfite and from about 40 to about 120 mmol/l of sulfite ions. A black-and-white photographic silver halide element comprises a support having disposed on each side thereof, a silver halide emulsion unit that comprises silver halide grains and a gelatino-vehicle, the silver halide grains comprising at least 95 mol% bromide based on total silver, at least 50% of the silver halide grain projected area being provided by tabular grains having an average aspect ratio greater than 8, a thickness no greater than 0.10 micrometers, and an average grain diameter of from about 1.5 to about 3 micrometers.
