The "reversal exposure" would have occurred DURING processing... somewhere around the mid-point (??) of development.Originally Posted by Tom Stanworth
Hmm... A thought ... did you use a developing tank? If it was a JOBO (??? I can't remember - did you say it was a 1500 series?), was the conical light trap in the cap (fits into the central "spindle") in place? That might explain light entering the tank during filling and emptying - if not during the development itself.
