Method of processing a photographic element containing electron transfer agent releasing couplers

A method for deriving a color negative film developer composition and processing conditions for developing a photographic film image which is optimized for subsequent digital scanning and digital image file manipulation, which allows for optimum rapid development processing of the film is disclosed. The process includes identifying at least one independent variable that has a first order effect on the density of at least one of the red, green, and blue dye images of the developed image, selecting a desired range of values for the independent variables identified, formulating an experimental design that includes desired independent variables over the desired range of values, performing the experiment to obtain statistically significant values for desired dependent variables, applying the values to a mathematical model capable of providing a formula for optimizing responses to the dependent variables, and using the formula to identify desired optimal developer composition and processing conditions resulting in an developed image in which the subsequent required digital scanning and digital image file manipulation is reduced. Also disclosed is a method for providing a color display image including developing an imagewise exposed color silver halide negative working film having at least two color records, with a color developer solution composition and under development process conditions derived in accordance with the above process, scanning the developed film to form density representative signals for the at least two color records, and digitally manipulating the density representative signals thus formed to correct either or both interimage interaction and gamma mismatches among said at least two color records to produce a digital record providing a display image having desired aim color and tone scale reproduction, such that the digital manipulation is minimized.

A method for providing a color image in an exposed color negative silver bromoiodide film element comprising contacting said element with an aqueous color developing composition having a pH of 9.0 to 12.0 and comprising a color developing agent, sulfite ion and an additional antioxidant wherein the color developing agent/sulfite ion molar ratio is less than 10:1 and greater than 0.55:1, and the sulfite ion/antioxidant molar ratio is less than 4.35:1 and greater than 0.25:1.

Method of use of stabilized rapid access color developers for color negative film

Rapid development of silver bromoiodide color negative photographic films and formation of high quality negative images suitable for scanning to produce display images of excellent quality is made possible by a novel developer solution composition and method of development. The solution is characterized by containing, in addition to the color developer compound and conventional photographic developer solution components, a water soluble pyrrolidone polymer, a high concentration of sulfite ion and a low concentration, or the absence of, bromide ion. In the novel method the developer composition contacts the exposed film at elevated temperature, e.g., 40 to 66&deg; C., for a short development time, e.g., 20 to 90 seconds. The developed image has image quality suitable for scanning and digital manipulation to produce a digital record for forming a color display image of high quality.
