Use the formula below undiluted. Your prints should be underexposed by approx. 15% as an increase in print density occurs. Experiment to find the best result for your needs.

Ferric Ammonium Citrate 8.0g
Potassium Ferricyanide 8.0g
Acetic Acid (28%) 265ml
Distilled water at 53C/130F 500ml
Distilled water to make up to 1000ml.

Test for any traces of fixer within the print
Soak prints in distilled water for approx 10 minutes
Place prints in undiluted toner and agitate
Remove the print from the toner just before desired tone is achieved
Fix prints in a non-hardening fixer
N.B: Prints will appear greenish at first but will wash to a clear blue in a water bath
Wash prints for 15 minutes in an acidified water bath. This is because alkaline water will weaken the blue tones.
