    I have shot two rolls of Ilford Delta 400 120 in my Hassy. I presoaked on both occasions for about 2 mins. (an old habit of mine). When I dumped out the water to put in the delveloper, a bunch of black crud came out with the water. Both rolls were almost completely clear, almost as if they had not been exposed at all. I have no experience with Ilford films, but I checked my camera out, and everything seems to be as it should. On the second roll I even pushed the development time a bit (Ilfotec DDX, 8.5 min. at 74%F) and still no images. This is making me crazy! Should I not be doing the pre-soak?

    I always presoak my film with distilled water. I can't imagine why it wouldnt work in your case. I am assuming it was a water presoak, from a clean container (not used for fixer, etc) and the temp was normal.

    Sounds like the emulsion is coming off in the presoak. Weird.

    Ilford should say in their film docs that a presoak is not required, especially for roll films. When you're doing tray development, a presoak is almost mandatory to ensure that the negatives don't stick to each other.

    However, a presoak will not cause the emulsion to come off!

    Try a roll without a presoak, and see what happens. If it happens again, then I would suggest that you have a bad batch of film.
    Cheers!

    It's not the pre-soak. The black stuff that comes off is the anti-halation backing. If I remember, Hassies have a dark slide. Did you remove it before exposing the film?

    I have made some of my best exposures on a dark slide.

    If all is working correctly, you can't fire the Hassy's shutter with the dark slide in - at least not on the one I used..

    i use ilford delta 100 film almost exclusively and always presoak. never a problem so far. i wonder, though, wouldn't the developer, being a liquid, take off the emulsion just as readily as plain water? sounds like a bad batch of film.

    Can you describe the "crud" in more detail?

    I love the smell of fixer in the morning. It smells like...creativity!

    Nor mine, either.

    I've read this ... and I wouldn't have a clue to why there wasn't ANY image at all.

    I know that Ilford recommends AGAINST a pre-soak; and the color film manufacturers recommend the same - more intensely - but they all suggest a degradation of the image - not that the image would be destroyed.

    The *only* explanation I can think of is ... FIXER at some time before developer. Does the affected film have ANY "edge markings"?

    According to the MSDA for Ifotec DDX, it is a Phenidone/Hydroquinone formulation. This means that it is susceptible to Phenidone oxidation (no color change with this!) and a consequent sudden and dramatic loss of developer activity.

    A Google search reveals that Ifotec DDX is described as "a lovely developer with a limited shelf life."

    Try a test piece of the film in a different developer.

    When you checked your Hassy out, did you remove the film back and fire the shutter while pointing the lens towards a light source? I once had a shutter failure that resulted in a couple blank rolls of film - shutter sounded ok but wasn't working.
