Water 125F/52C | 750 | ml |
Ferric Ammonium Sulfate | 45 | g |
Potassium Citrate | 75 | g |
Sodium Sulfite (anhydrous) | 30 | g |
Citric Acid | 22.5 | g |
Sodium Thiosulfate (Hypo) | 200 | g |
Cold water to make | 1000 | ml |
Mixing Instructions: Add chemicals in specified sequence. Do not substitute Sodium Citrate for Potassium Citrate as the rate of reduction will be considerably slowed. |
Dilution: Use undiluted, or 1+1 for slower action. |
Usage: Immerse a clean, fully fixed and washed negative into solution for 1-10 mins at room temperature (approx 18C-21C), then wash thoroughly. |
Notes This is a modified version of original Belitzski Reducer. Hardener should not be required with modern emulsions, but if you encounter any issues with emulsion softening, the use of a hardener prior to treatment is recommended. |
