    Re: What can cause TINY TINY white spots on a neg?

    From my experience, Freestyle is good to work with on such matters. I had a problem a few years ago with a paper that was not behaving as it should. They replaced the entire order without a problem. Of course, it probably helps to have been a loyal customer for many years!

    I hope you get tis sorted out, and report back. Good luck!

    Oh dear. That is exactly the issue I had with the last two rolls of Fomapan 200 in 120 size. I love this film and so far have had no problems with sheets but I haven't had a good roll in 120 from the last 3 years. One lot had a backing paper, storage issue, which put me off buying again and I never heard back from Foma about it; then at the end of last year I tried another two rolls and experienced the problem you have detailed.

    I need to place an order for both 4x5 and 8x10 but am very reluctant to do so now. Have you contacted Foma about this or B&H?.

    Edit: Actually I've looked at mine and realise that your marks are opposite to mine and that of the OP who is reporting WHITE marks on the NEGATIVE resulting in black marks on a positive image.

    The OP reported tiny white dots on the positive image and purple dots on the negative image that create the white dots in the positive image. Please see my original post.

    FYI, got a new box of 8x10 EDU 400 today via UPS. Freestyle was able to replace. Hope they run a test with that emulstion so it doesn't seem I'm really crazy!

    Any updates on this? I just did my first test shot from a box of fomapan 100 (4x5) last night and got the purple spots. If I’d seen this thread then maybe I would have just bought fp4+ again instead.

    I did 1 shot of foma100 at 50 and my last sheet of fp4+ at iso 100 and I definitely like fomapan better... other than unreliability.

    I was hoping someone would come on with a solution to dissolve the spots :-/

    Yes, the update is I sent it back to Freestyle and they got me a new box. Unfortunately, there isn't a way to dissolve the spots. Like the old Prego commerical says "It's' in there".

    "Sit in Fix for a while."
    Not agitating in the fix can allow sediment of undissolved chemicals and other materials to settle on the film. Agitation is a good thing to do until the filmis hung.

    I agree with Doremus on the particulate matter in the chemicals. I've had that happen to me before. I mix all my chemicals with distilled water, use developer as a one shot, and when I use the fixer I filter it before use to reduce any particulate matter. That resolved the problems for me.
