    Ok so I have shot another roll loaded indoors and had it professionally developed. Still light leaks on the top and bottom edges. So it seems like it's a film spool issue. Is there anything that I can do about this? Sometimes it does cuts into the frame a little bit, but the light leaks are just annoying to me.

    Light leaks on B&W but not color film

    Spools tend to be SLIGHTLY different distance apart from manufacture to manufacturer, if you shoot some kodak, and follow it with ilford, the take up spool will have a different width than the original, couple this with not shielding the roll from the sun, and you'll get some light leak at the edges.

    I think the problem is how carefully you are shielding the film once it is shot. Which seems not very well, considering how much leak there is. There's a reason the spools say they should only be loaded and unloaded in subdued light.

    Check to make sure the camera back is closing tightly, and stays tight(no movement at all), and make sure when you open a fresh roll of film that it is tight as possible to start with. It could be some of the rolls you have may be loose already, or you are allowing them to loosen when loading.

    You can tighten the film and backing paper on the spool and fold under the backing paper tongue before you remove the spool from the camera.

    I spin the spool with my fingers and use my thumbs to provide tension.

    For what it's worth, I've had similar problems with light leaks on Ilford FP4+ and HP5+ 120 film. Unless the films are changed out in very subdued lighting, the edges of the negatives darken up from light leakage exactly the way your pictures show. However, I've never had a problem with Fuji or Kodak E6 films experiencing light leakage like that when I've changed them out under the same lighting conditions.

    I went through a lengthy troubleshooting process for exactly the same reason about two years ago to try and determine if the problem was because of the camera or a bad film back and ended up coming to the conclusion that the Ilford film's backing paper must not be as tight up against the edges of the reels as Fuji's or Kodak's. It must be allowing just enough light through to expose the edges when you're stuck with changing films out under fairly bright light. When I'm able to avoid doing that, the negatives are fine but it isn't always possible. The fact it was kind of an intermittent problem because I was sometimes able to change films in very subdued light and sometimes not certainly made figuring this one out more difficult...

    Boy, is this harder to explain then to show!

    When I get to the end of the film, the backing paper tongue and the adhesive coated "Exposed" strip are both loose at the end. If you don't somehow make that tongue shorter, the "Exposed" strip won't seal in a way that will reliably hold the backing paper tight on the spool. So you need to either cut off the tongue or, preferably, fold it under so that the end of the backing paper is a straight line, and the "Exposed" strip can make a good stick-on seal.

    Since getting into MF last year, I see this a lot. It does seem like Ilford is more prone to it than Kodak, but then again, I'm generally using Ilford in my folder, which means I'm loading and unloading outdoors quite a lot. My Kodak film use is generally in my RB67, and I usually load up a few backs indoors before heading out to a shoot. So there's enough variation in technique there to explain the difference.

    Anyway, I've never had exposure from an edge leak like that go far enough to effect an image.
    I shoot digital when I have to (most of those shots end up here) and film (occasionally one of those shots ends up here) when I want to.
