    Camera fault or development (loading on the reel) issue?

    Just stepped out of the darkroom and am drying some negs from one of my Minolta XG-1 (HP5) and noticed that a few frames have dark marks on them and some frames seem to not have the space in between (like the are dark as a neg = light in reverse)! They are still hanging, so I haven't had a chance to really investigate, but I'm wondering if it could have been me rushing in the darkroom and loading them wrong or if my film advance thingy is acting up. I will post an example this evening when they are dry; but wondering in the mean time if anyone has any experience with this.

    Without more information this is just a quick assessment, it sounds like the film advance is not working correctly. The camera probably needs a CLA.

    Well crap. Scanned a few and it looks like a light leak for sure. Here are two random shots that are affected :

    first one is mid frame
    second is between frames

    Not sure it is a light leak; according to the manual this camera has a horizontal-traverse focal plane shutter. If the two curtains moving horizontally are out of sync you may end up with such vertical band that looks like a flare. I'm not a technician, this is my 2c in the matter. I hope more people chime in. This camera is 30+ years old, it may need a CLA.

    Definitely looks like a camera problem. Problems during development don't often leave sharp straight lines of demarcation. A problem with the shutter or film advance could create patterns such as you have shown.

    Okay, where is the best place to have it serviced? Find something local or is there an "old minolta guru" that I should send it to?

    Check first that it isn't a light leak due to the back not closing properly. How are the light seals?

    Back closes firmly and tightly - seals are there - sorta degraded, though. The outward side is sticky in the area where it seals up, though.

    Want to point out that the line is always there, now that I look closely. It's either a sharp white line, or a faint wide bar. It moves along the frame in each shot and is not in the same location. Would that be a curtain seam or a shutter issue?

    Either way, I have a backup body that was donated to me (since I LOVE this little camera so much, I had to have another one) but it's the same age, and I am wondering if it will eventually meet this same fate.

    Some more frames to study: (note, example #5 was on a previous role of film ... and when I started to notice this happen - and it was less prevalent then)

    Looks like perhaps your shutter curtains are not coming to rest in a closed position after a shot, but before you advance the film (and even while you are advancing the film in your case). This lets light pipe in until you advance the film/cock the shutter.

    If this is the case, the longer you wait before advancing the film, the denser the light leak will be on the frame. Using that premise, you can test this on a tripod. Do some shots where you advance immediately. Do others where you wait different periods of time before advancing. Do others where you cover the lens immediately after taking a shot, and then advance the film with the lens covered. But don't change the position of the camera between shots. The amount of light coming in will not be constant shot to shot if you are moving the camera. Make sure to keep track of what you did on each frame.

    FWIW, my Leica III has the same problem. Not worth fixing IMO. The repair is 2 or 3 times the replacement value of the camera.

    Another test would be to make flash photos in a very dark room, at night.
