Glycin hydroxide developer for tray use.
|Mix chemicals in order.|
|Water to make||1||liter|
For very badly underexposed negatives or for strong contrast, use full strength. For softer negatives, dilute with water up to 1:5.
This is an excellent formula for “stand-by” purposes. If a negative shows no image with a regular tray developer, it can be rinsed for a few minutes in plain water and transferred to a glycin-hydroxide bath and if there has been any reasonable exposure a usable negative will result. The temperature should he kept below 18.5°C and formalin (1–2 drops per 30 mililiters of developer ) should be added just before using to prevent undue emulsion-softening.
