Abstract: Recovering the dye image on film in electronic film development following a latent holding stage obviates the problem common in prior art electronic film development of film image destruction. Recovery of the image is accomplished using a developing agent containing couplers to form a dye image. These dyes do not affect the infrared scans of the image. Upon complete development of the dye image, further dye formation is halted by the application of a coupler blocking agent, while silver development and electronic scanning may continue or halt. After halting dye formation, the film is stable for an arbitrary time in a latent stage and may be dried and stored. Following this latent stage, silver is removed from the film with a bleach-fix leaving a conventionally usable film image.

Abstract: A color image can be obtained from a color photographic element by multiple color development steps. The first color development is carried out in the usual manner after imagewise exposure. The second color development step is carried out after bleaching with a rehalogenating bleaching agent, and is used to develop only rehalogenated silver halide. This specific development is possible by either using a chloride rehalogenating agent in the bleaching solution, using a sulfite fixing agent before bleaching, or by fogging the element between bleaching and the second color development step.
