This invention relates to a photographic element comprising a support having situated thereon at least one silver halide emulsion layer, the element further containing an image modifying coupler which upon reaction with oxidized color developing agent during processing forms a dye, said image modifying coupler represented by the formula ##STR1## wherein COUP is a photographic coupler moiety;

Silver halide element containing triazole inhibitors

A photographic element comprising a support having situated thereon at least one silver halide emulsion layer, the layer containing a photographic coupler represented by the formula

Indazole containing coupler

A photographic element comprising a support having situated thereon at least one silver halide emulsion layer, the layer containing a photographic coupler represented by the formula ##STR1## wherein COUP is a coupler moiety having a coupling site to which T.sup.1 is attached; T.sup.1 is a timing or linking group which releases from COUP during processing and which functions by electron transfer down a conjugated chain, or by nucleophilic displacement reaction, to release from HETERO; HETERO is a heterocyclic group containing at least two heteroatoms independently selected from oxygen, nitrogen, or sulfur, wherein one of the heteroatoms is directly attached to T.sup.1 ; R.sup.1 and R.sup.2 are independently selected from hydrogen, or an aliphatic, carbocyclic, or heterocyclic group, or may be bonded together to form a 5, 6, or 7 membered ring; and PUG is a photographically useful group.
