Photographers' Formulary Sepia Sulfide 221 is a classic bleach and redevelopment toner that produces rich permanent sepia-brown tones. Most types of paper tone well with this process, including resin coated paper. The bleach contains potassium ferricyanide that changes the metallic silver to a silver salt. After bleaching the print is then redeveloped in sodium sulfide.
