The best developers in my opinion are sodium citrate or potassium
oxalate. Potassium oxalate prints a bit faster and has slightly
better keeping qualities, but is more expensive.

Toning with gold, pallaidum or platinum should be done *before*
fixing. If you use selenium to tone you should fix the print first,
and give it a long wash before toning. Selenium is highly reactive
with silver nitrate and if there is any in the print when you tone
the highlights will be degraded.
