This formula, similar to Kodak D-72, is recommended for most high quality enlarging papers, and can also be used for development of roll, pack and sheet film when brilliant negatives are desired. Oriental VC Plus paper exhibits a pleasing palette of subtle warm tones using the normal 1:2 dilution, and can be toned a deeper richer brown with Sepia Sulfide 221 Toner.
STOCK SOLUTION
| Chemical | Amount | Units |
|---|---|---|
| Water (125°F/52°C) | 750 | ml |
| Metol | 3 | g |
| Sodium Sulfite (anhy) | 44 | g |
| Hydroquinone | 12 | g |

USAGE
PAPER DEVELOPMENT: Dilute 1 part stock solution with 2 parts
water.
Develop 1 to 2 minutes at 68°F/20°C. For softer and slower development
dilute 1 to 4 and develop 1½ to 3 minutes at 68°F/20°C. For greater
brilliance, shorten the exposure slightly and lengthen the development
time. For greater softness, lengthen the exposure slightly and shorten
the development time.
FILM DEVELOPMENT
Dilute 1 part stock solution with 1 part
water and develop 3 to 3½ minutes at 68°F/20°C. For softer results,
dilute 1 to 3 and develop 3 to 3½ minutes at 68°F/20°C.
NOTE
GAF-125 is similar to SA Warm-Tone Paper Developer except the SA versions
substitutes 30g Potassium Carbonate (mono)
for the 65g Sodium Carbonate (mono) used
in the GAF-125 formula.
Ansco 125 is the same as GAF 125, with Ansco 103 and
Ansco 135 being quite similar to GAF 125. Kodak D-72 uses 80g of
sodium carbonate instead of 65g.
