Abstract

A ferric-EDTA bleach regenerator composition can be mixed with bleach overflow to provide a bleach replenisher for reversal color silver halide photographic processes. The bleach regenerator composition has a critically controlled pH between 6.0 and 6.5, and comprises a total bromide ion concentration of at least 210 g/l, and ferric ion in an amount of at least 50 g/l. At least 50% of the bleach overflow and the bleach regenerator composition are mixed in at least a 1:1 volume ratio. After pH adjustment to from 5.4 to 5.6, the pH adjusted replenisher is supplied to the bleach tank for use in the process.
