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.
