    Weird film spotting problem

    Anyone know what is causing the issue in the attached film scan? I don't think it is from bubbles because it only happens with Fomapan. I have used several different films and have never had this problem. It is not in every frame either. It has ruined many of my photographs over the past year but this one is the worst. Also is there a printing solution for images with far less spots? The film is Fomapan 100 and the developer in Rodinal 1:50.

    Nice photo. If you suspect it is the film, why keep using it? Never had problems with Kodak, Ilford, or Agfa (now gone).

    I am already switching over to FP4+ but I am curious about the problem. I know several other members that use this film and haven't had these problems.

    These look like air bells to me. If they are, the solution I found to air bells is to rap the tank hard after agitation. It seems to me more important to catch this early in processing, when it is still dry. Once the film is totally wet, bubbles would tend to move around.

    OK. Well, you could try a plain water wetting before the developer?

    Bill, that is exactly what I do. That is what makes this so confusing.

    I should also mention that I use water for stop as people have reported issues with stop bath. I also don't pre-soak the film. Should I start?

    I agree with Bill. That is exactly how I would have responded. The tank-tapping should help.

    Why not use a chemical stop? I am not convinced that pre-soaking would remedy the issue.

    Chemical stop is known to cause pinhole problems with Foma emulsions. As I have said I rap the tank on the counter after each agitation.

    Both Kodak and Ilford say NOT to presoak film.

    What is your agitation scheme. Does it include rapping the tank sharply on the counter to dislodge any air bubbles?
