    If they are very faint and on the base then you may have nothing to worry about. I noticed a few scratches on my 35mm film base and thought they would be ruined. I printed them with a diffusion enlarger and could not find any problem with the prints. Good luck.

    On the base side, worry not unless you really see something on the print. Use a low f/stop in the enlarger as another possible correction if you do see something.

    It might not be your camera. Did you use a wetting agent? Did you squeegee the film when drying? Did you filter ALL of the water, even the wash water? Like with a real filter, not just one of those wire meshes? Unless something exceptional happened I would not suspect the reels.

    Looks like Sean already located the source of the problem - it is either the camera (most likely) or the film canister (see above quote). Seems like there was another thread this past week and someone suggested using a pair of hose to located any burr, etc. Sounds like the best solution.

    Sean, are the scratches always in the same place on the negative. Since it is on the base and not emulsion side, that gives you a place to look - somewhere on the camera back from the roll to the take up spool. Where were they in relationship to the film when the back was open. I think you have already found it, you just don't know it yet.

You need to clean the cassettes occasionally for the bulk loads and toss them when they get rough looking. I've also seen cheap cassetes get a fine bit of rust inside them and make scratches.
    Aother boo boo I've done is to forget to open the gate on the reloader when I start winding the film in. Talk about scratches!
    Hi Gary, I am overly protective with camera and film, I'm going to have another look at the camera and see what I can find. It's also factory loaded 24exp rolls

    Thanks for the replies everyone. Well my water is rainwater and filtered through a 1micron filter so I think it's ok. In the past I've always wet my fingers with a little wetting agent and squeegeed the film that way, and at first I thought maybe that did it, but after looking at the roll of film that was currently in progress I could see scratches so I'm pretty sure it's the camera. Some good news is that the scratches did not show in the film scans, usually when they show in my scans I know they'll show on the print.

    Are you bulk-rolling? Could also be your loader.

    Nose oil (as already said). It works better than it sounds.

    Skin oil has been my usual cure for such catastrophes. Wipe it across the scratch with a thumb, but don't leave fingerprints. The side of your nose or behind your ear works as a source.

    hmm, how do you wipe oil from your skin to the neg without leaving smudges or fingerprints?
