Abstract
A method of developing a latent image on a photographic element (such as imagewise exposed photographic film) by absorbing a dye precursor into the film, applying a developer solution to the film to develop the latent image and form a dye in the film, scanning the film with light, and detecting at least one of light reflected away from and light transmitted through the film.
Claims27
A method of developing a latent image on an exposed photographic element, comprising:
- (a) applying a dye precursor to the exposed photographic element;
- (b) applying a developer solution to said photographic element, thereby developing said latent image and forming a dye in said photographic element;
- and
- (c) scanning said photographic element with light while said latent image is developing.
A method of electronically developing a latent image on exposed film, comprising:
- (a) applying a developer solution to the film thereby developing the latent image on the film and imagewise forming a dye in the film;
- and
- (b) scanning said film during development with light of a wavelength chosen such that said dye attenuates said light.
A digital film processing system for use in electronic film development, comprising:
- (a) a dye precursor supply station configured for applying a dye precursor solution to a film;
- (b) a developer supply station configured for applying a developer solution to the film;
- and
- (c) at least one scanning station for scanning the film with light after application of the dye precursor solution and the developer solution.
An aqueous dye precursor solution, consisting essentially of a coupler capable of forming an infrared-absorbing dye.
A developed photographic film comprising a plurality of emulsion layers, each of said layers having a silver and dye image, wherein the same dye is present in each of said layers.
