Ansco 72 Glycin Film Developer

FormulasThis clean-working formula is recommended for use with commercial films in reproduction work when a comparatively low maximum denisty is desired. It is also suitable for development of roll, pack and sheet film providing a long scale of tonal gradation.


Hot Water (125F or 52C) 800 ml
Sodium Sulfite, anhydrous 125 g
Potassium Carbonate 250 g
Glycin 30 g
Water to make 1 L


TANK DEVELOPMENT: Take one part stock solution, fifteen parts water and develop 20 to 25 minutes at 68 F (20 C). (Ed note – this looks like one of the few places American ounce measurements are superior – one ounce of developer and 15 ounces of water will fill a 120 stainless steel tank.)


TRAY DEVELOPMENT: Take one part stock solution, four parts water and develop 5 to 10 minutes at 68F (20C).
