ABSTRACT:
A method of processing a silver bromoiodide photographic element comprising contacting the photographic element with a color developer for less than 120 seconds; wherein the photographic element comprises a support and more than one dye forming unit, and wherein the dye forming unit closest to the support contains an electron transfer agent releasing compound represented by the formula:in-line-formulae description="In-line Formulae" end="lead"?CAR-(L)n-ETAin-line-formulae description="In-line Formulae" end="tail"?wherein:CAR is a carrier moiety which is capable of releasing -(L)n-ETA on reaction with oxidized developing agent;L is a divalent linking group, n is 0, 1, or 2; andETA is a releasable 1-aryl-3-pyrazolidinone electron transfer agent having a calculated log partition coefficient (c log P) greater than or equal to 2.40 bonded to L or CAR through either the nitrogen atom in the 2-position or the oxygen attached to the 3-position of the pyrazolidinone ring.
