A method of processing photographic color papers is carried out using a photographic bleach-fixing composition in a bleach-fixing step that is carried out for less than 60 seconds. The bleach-fixing composition comprises certain aliphatic or aromatic sulfur-containing compounds that include a —N═C(SH)—group. The bleach-fixing composition can be prepared from a two-part bleach-fixing kit having two solutions that can be added directly to a processing chamber or premixed to form a replenisher solution.
