    Fading to black exposures – Please help.

    I've been shooting with an Olympus OM-1 for a couple months now. I love the camera to death, but it has one problem. Occasionally, and I think only when shooting outdoors, only the left half a frame will be exposed and will fade to black on the right.

    Here is a photo to demonstrate what's going on:



    If anyone has any ideas about why this is happening, please let me know. I wouldn't want this to stop me from using this camera.

    If the shutter moves horizontally, then it is a shutter problem.

    Firstly, welcome to APUG.

    As far as your problem, could it be a camera strap dangling or a gloved finger?

    That's also my first thought. I've seen similar frames, indeed only occassionally (and vertically, because the shutter on my EOS 650 moves vertically) exactly due to that problem.

    "Only when shooting outdoors" is another hint in that direction; I would translate that to "only for faster shutter speeds".

    Edit: Googling reveals that the OM-1 has a horizontal shutter indeed. Yet another indication that the shutter is the culprit.

    Only for faster shutter speeds and only in cold weather?

    One of my students had the same problem. Have of the frame was exposed. We looked at the shutter of her 35mm and it wasn't opening all the way. I will start looking at that first.

    Shutter problem

    The second curtain is closing too quickly and accelerating, causing the frame to be progressively underexposed as the curtain moves horizontally across. At slower speeds it might not be as noticible, but outdoors, in bright sunlight, where faster speeds are often necessary, it will rear its ugly head. There is no quick fix that I know of. All the speeds will need adjustment.

    It looks to me like the leading shutter curtain is quickly slowing to a halt at exposure time. Perhaps a bent metal guide edge? Is the effect precisely the same at all speeds?

    It is a shutter problem. Your camera is telling you to have it CLAed ASAP ... SG
    Warning!! Handling a Hasselblad can be harmful to your financial well being!

    Nothing beats a great piece of glass!
