Response to drying marks on Agfapan 25

Peter, It sounds like the classical air bell problem. The older emulsions where prone to this if you didn't rap the tank hard to dislodge the air bubbles from the film when you put it in the developer. If this isn't the case, I would run the film through the developing stage and do another quick fix and Perma wash again. This will not do anything to the film other than soften the emulsion and "usually" clear up the anomilies. Hope this helps, Cheers
