Response to Sodium Sulphite in Rodinal

Pat Gainer has been working on some very interesting uses for l- ascorbic acid, one of which is adding 4g/L to working dilutions of Rodinal. This has the effect of sodium sulfite--finer grain--without the attendant softening of the grain structure as sodium sulfite would (provided you used enough of it to lessen Rodinal's prominent grain).
