Method of processing originating photographic elements containing tabular silver chloride grains bounded by (100) faces

A method of increasing the photographic speed of an exposed silver halide color photographic element at least 0.04 log E for a development time of 120 seconds or less, comprising:

• developing an exposed silver halide photographic element in a color developer solution containing a p-phenylenediamine color developing agent in the presence of a 1-phenyl pyrazolidin-3-one compound;
• wherein the silver halide photographic element comprises a radiation sensitive emulsion in reactive association with a development inhibitor releasing compound and containing a silver halide grain population comprised of grains comprising at least 50 mole percent silver chloride, based on total silver forming the grain population projected area, wherein at least 50 percent of total grain projected area is accounted for by silver halide tabular grains
• (1) bounded by {100} major faces having adjacent edge ratios of less than 10 and
• (2) having an average aspect ratio of at least 2;
• and
• wherein the silver halide content of the photographic element comprises at least 50 mole % silver chloride and no more than 2 mole % silver iodide,
• the increase in speed being determined relative to processing the same photographic element under the same conditions but in the absence of a 1-phenylpyrazolidin-3-one.
