The photographic element of the invention provides a support bearing at least one photographic silver halide emulsion exhibiting low developability and having associated therewith at least one high dye-yield coupler that releases a dye or dye precursor having an electrically neutral dye chromophore. The invention also encompasses a process for forming an image in an element in accordance with the invention.

Photographic element with silver halide emulsion layer of low

The invention is accomplished by providing a combined process of chemical and spectral sensitization comprising providing a silver halide emulsion, adding a sulfur or gold chemical sensitizer, adding a finish modifier ##STR1## wherein X is --O--, --S--, --Se--, ##STR2## Y.sup.1 and Y.sup.2 individually represent hydrogen or an aromatic nucleus or together represent the atoms completing a fused aromatic nucleus; R is hydrogen or lower alkyl of from 1 to 5 carbon atoms; and R.sub.1 is a hydrogen or methyl, provided that Y.sup.1 and Y.sup.2 individually represent hydrogen or an aromatic nucleus when R.sub.1 is hydrogen, adding dye, and

Sensitivity increase from alkynylamineazole, sensitizing dye, and

Hollow silver halide grains and a process for their preparation are described. The hollow grains have high surface area/volume ratio and enhanced light absorption.

Hollow silver halide grains and process for the preparation thereof

Siliver halide photographic elements are disclosed comprised of blended emulsions. An improved relationship between speed and granularity can be realized when a blended silver bromide or bromoiodide emulsion is comprised of a high aspect ratio tabular grain emulsion containing at least one spectral sensitizing dye and a low aspect ratio grain emulsion.
