Unblinking Eye
Developing Times for Rodinal

 

Rodinal contains a high-acutance, low-fog developing agent (p-aminophenol hydrochloride).  At the higher dilutions recommended here it gives a slight compensating effect and good edge effects.  Agitation should be for 10 seconds once each minute.  Times are for roll film in small tanks, optimized for printing with a cold light head.
