Claims
- 1. A method of producing a dye image having improved signal-to-noise by processing an imagewise exposed color photographic element containing at least one silver halide emulsion layer, the emulsion layer comprised of both latent image and non-latent image containing grains, and having a distribution of Compound X, Compound X being either a ballasted coupler capable of reacting with an oxidized developing agent of a developing solution, or a ballasted developing agent capable, in an oxidized state, of reacting with a component of a developing solution, where the concentration of silver halide is in stoichiometric excess relative to the concentration of Compound X, said method comprising:
- A. contacting the photographic element with a first developing solution to develop the latent image containing grains and to imagewise convert the distribution of Compound X to a first dye;
- B. rendering the non-latent image containing grains developable; and
- C. contacting the photographic element with a second developing solution to develop the non-latent image containing grains, and to convert residual Compound X to a second dye;
- wherein the first dye has a spectral characteristic which is non-coextensive with that of the second dye.
- 2. A method according to claim 1 wherein Compound X is a ballasted coupler.
- 3. A method according to claim 2 wherein the emulsion layer is negative-working.
- 4. A method according to claim 3 wherein the non-latent image forming grains are rendered developable by fogging with a light source, or by chemical fogging.
- 5. A method according to claim 4 wherein subsequent to contacting the photographic element with the first developing solution, and prior to rendering the non-latent image containing grains developable, the element is contacted with a stop bath and then washed.
- 6. A method according to claim 5 wherein subsequent to contacting the photographic element with a stop bath, but prior to rendering the non-latent image containing grains developable, the photographic element is contacted with a black and white developer which completes development of the partially developed latent image containing grains without developing the non-latent image containing grains.
- 7. A method according to claim 3 wherein subsequent to contacting the photographic element with the second developing solution, the element is washed and contacted with one or more bleach, fix, or blix solutions.
- 8. A method according to claim 1 further comprising the step of scanning and digitally processing the photographic element's reversal dye image.
- 9. A method according to claim 1 wherein the conversion of Compound X to the first dye upon contact of the photographic element with the first developing solution, and the second dye upon contact of the element with the second developing solution, occurs in the presence of an electron transfer agent.
- 10. A method according to claim 9 wherein Compound X is a ballasted developing agent.
- 11. A method according to claim 10 wherein the emulsion layer is negative-working.
- 12. A method according to claim 11 wherein the non-latent image forming grains are rendered developable by fogging with a light source, or by chemical fogging.
- 13. A method according to claim 12 wherein subsequent to contacting the photographic element with the first developing solution, and prior to rendering the non-latent image containing grains developable, the element is contacted with a stop bath and then washed.
- 14. A method according to claim 13 wherein subsequent to contacting the photographic element with a stop bath, but prior to rendering the non-latent image containing grains developable, the photographic element is contacted with a black and white developer which completes development of the partially developed latent image containing grains without developing the non-latent image containing grains.
- 15. A method according to claim 14 wherein subsequent to contacting the photographic element with the second developing solution, the element is washed and contacted with one or more bleach, fix, or blix solutions.
- 16. A method according to claim 15 further comprising the step of scanning and digitally processing the photographic element's reversal dye image.
