DEVELOPMENT PROCEDURES
1. Pre-soak for five minutes. The pre-soak is optional with tray and tank development (except with minimal and stand development), but it is absolutely essential with rotary processing.
2. Development for the time required in tubes, drum, tray or tank according to the instructions that follow.
3. Stop bath. I recommend the use of a dilute acetic acid bath of about 1/4 to 1/2 normal strength. If the stop bath is too strong it will reduce image stain.
4. The use of an
alkaline
fixer is recommended (Kodak or Ilford rapid fix works just fine).
5. One minute in a hypo-clearing agent. I use a 1% solution of sodium sulfite.
6. Wash under running water for 30 minutes.
