An inexpensive fine-grain developer as published in “British Journal Photographic Almanac 1941”.
The following is an inexpensive fine-grain developer which is stated never the-less to give very excellent results.
|Mix chemicals in order.|
|Sodium sulphite anhydrous||136||grams|
|Kodalk or Sodium metaborate||57||grams|
|Water to make||1||liter|
For use, this stock solution should be diluted with eight volumes of water. Development times for super speed pan- chromatic material are of the order of 30 min. at 18.5 °C, or 22 min. and 18 min., respectively, for fast and for extra fine grain material.
The developer may be thrown away after use, but the stock solution will keep well if properly stoppered.
