    Same here, I am almost 100% ilford user now, better costumer support (and products) do not exist. please post on the forum when you know what has gone wrong, so we all can learn.

    Yan,
    Your problem looks to me to an issue with your final wash/rinse. As you say that its occurred on different formats and different sizes in Ilford's range, I can't see the materials being at fault. Apart from all else, I suspect that a lot of other people with film from those batches would be hopping up and down as well! I occasionally used to suffer from marks on negatives. I live in a very soft water area and concluded that I was overdoing the wetting agent in the final rinse. I now use literally only one drop of wetting agent in a full tank of water, then tip that away and have a "final final" rinse in just plain water. No problems since I started doing that.
    Simon's kind offer of advice and investigation is typical of the service we enjoy from Ilford (other firms, not just photographic, should take note!) but somehow I think you're wasting your hard-earned money posting your negs to England!
    Hope you get to the bottom of the problem, whatever it is!
    Steve

    Steve, thanks for your attention. When it happened in the first time I though the same. So i washed it again and again. Nothing, the marks were still there. I do think the problem can be with something that I´m doing. But whar really amazes me is that just one roll in the same tank came out with the marks. When I developed FP4+ I put 2 rolls in the same tank. One came with the marks, and the other not. Both rolls got the same soup, same water, same final rinse. So why one has the marks so consistent and the other is so clean? If there were some problems with the water, the final rinse or anything shouldn´t both rolls come with the marks. Here are some shots from the roll that I developed with the one with the marks.





    As you can see, they´re clean. No marks at all.

    Once again, thanks a lot for your attention with my problem. I appreciate.

    Because one was on top, where all the bubbles of the frothing 'soup' are, the other below, fully submerged.

    Put more liquid in the tank, and use less photoflo (and rinse the tank and spools thoroughly before using them again).

    I spent what felt like a long time looking at those two images to spot the problem before I scrolled down and saw that line!

    It does make sense

    Did the two FP4 rolls come from the same bulk roll, or were they bought at the same time from the same place? If the former, they're definitely from the same batch and if the latter then it's highly likely. Either way points to a processing issue rather than material. I don't know how the batch number is displayed on the film (probably bar codes these days) but if you could find something that looks like a batch identifier and they are both the same, perhaps you could go some way to ruling out the material.

    I'm sure it's a processing error.
    Bubbles, leaving their mark... nothing else does that.

    Ilford film batch code for 120 is a 4 digit number on the edge that has the Ilford name, eg. Ilford FP4 Plus 3997.
    It's repeated every 3 inches or so. No idea about 35mm but suspect similar.
