I started developing Agfapan 25 at home because drying marks were produced by commercial development. This film has to be the most sensitive to drying technique I have used.(posted 8739 days ago)Have you tried it with forced air of some kind, even just a little fan? I used my shower with the window open, so I had a tiny amount of airflow. What about running your shower fan when you hang the film in there?
I have used both Photoflo and LFN at recommended mixtures and have not had these problems, but my drying environment does contain just a little air flow.
What about using compressed air on your film? When you hang it up, use compressed CO2 to whisk the excess water from the film.
