Ansco 221 Sepia Photographic Toner

FormulasThis toner is recommended for warm-brown sepia tones.


Solution 1

Hot Water (125F or 52C) 750 ml
Ferricyanide 50 g
Potassium Bromide 10 g
Sodium Carbonate, monohydrated 20 g
Water to make 1 L


Solution 2

Sodium Sulfide 45 g
Water to make 500 ml


For use as described below, dilute one part Solution 2 with eight parts water.

IMPORTANT – Be sure to use sodium sulfide, not sodium sulfite, in compounding the redeveloper. Also use clean trays, free from exposed iron spots, especially with bleaching bath. Otherwise blue spots may form on prints.


Prints should be washed throughly and then bleached in Solution 1 until the black image is converted to a very light brown color (about 1 minute). Prints should then be washed for 10 to 15 minutes and redeveloped in diluted Solution 2.


Redevelopment should be complete in about 1 minute.s After redevelopment the prints should be washed for about 30 minutes and then dried. If the toner should leave sediment which results in streaks or finger marks on the surface of the paper, the print should be immersed for a few seconds in a 3% solution of acetic acid, after which a 10-minute washing is necessary.
