Abstract:
A method of forming a viewable image from a scene exposed onto a color negative photographic film element and for producing a color image suited for conversion to an electronic form and subsequent reconversion into a viewable form comprising:color developing an imagewise exposed color negative photographic film element with a color developer having a pH of from 9 to 12.5, and comprising: a color developing agent at a concentration of 0.01 to 0.1 moles per liter of solution, added bromide ion at a concentration of less than 0.06 moles per liter of solution, sulfite ion at a concentration of 0.00 to 0.25 moles per liter of solution, and a pH buffering agent at a concentration of 0.08 to 0.5 moles per liter of solution; said color development being carried out by contacting said film with the developer for a period of 20 to 90 seconds at a temperature of 40Â° C. or greater; said imagewise exposed film element comprising a support and, coated on the support, a plurality of hydrophilic colloid layers, including radiation-sensitive silver halide emulsion layers, forming layer units for separately recording blue, green, and red exposures, each of the layer units containing dye image-forming coupler chosen to produce image dye having an absorption half-peak bandwidth lying in a different spectral region in each layer unit, WHEREIN the element comprises a development inhibitor releasing compound in at least one layer unit, at least one of the layer units contains two or more emulsion layers differing in sensitivity, the layer units each exhibit a dye image gamma of less than 1.0, the element exhibits an exposure latitude of at least 2.7 log E, where E is exposure measured in lux-seconds, and a light sensitivity of at least ISO 50, the gamma ratio of each of the red, green and blue light recording layer units is between about 0.80 and 1.30, and the average layer thickness is 1.5 micrometers or less.
