HELP: Camera or Processing Fault ?

    hi,

    i had a roll of Kodak EB-3 developed by a local lab. but the result is
    so weird, expect 5 frames in the beginning, all remainds exposures are
    total transparent plastic with only ( not very ) dard strips sperated
    each of them in the normal vertical border positions.

    the lab said, i over exposured. i don't believe that. to make the
    darkest part of the subject as total transparent, it need about 7 stops
    of over-exposure, and because i use my camera always in M mode, it
    sounds impossible.

    but i checked my camera, and exposured another roll of cheap negative,
    found no problem.

    so i want to know, what possiblly the fault came from? can the
    processing itself cause the result? thanks.

    sorry, the 'expect' should be 'except'

  3. If the edges/frame dividers are the *same* as the rest of the film,
    then it's you, or your camera's fault.
    If they are slightly faded, with the fade 'emanating' outwards from the
    image area, then it could just be the leakage one might expect from
    severe over exposure - again, you and/or the camera are the problem.
    If they are *very* faded or invisible, then it could be either:
    - a processing error, but it is unusual for processing to go that crazy
    half way along a film strip.
    - accidentally exposed film - either by you (opened the camera back?)
    or the lab (oops, started pulling the film out and forgot to turn the
    light out...) - again, fairly unlikely in this age of automation...

    Take a picture of the film and post it somewhere...

    not the case
    yes, it is the case. the dividers are 'very' faded but still
    apparently visible.
    i think, i believe i did not opened the back. so, if it were my
    camera's fault, so how can it do that ? someone guesses that my len's
    aperture is not reduced when exposured those frames, is that possible?
    if so, why it now works well?

    another clue is, that those frame numbers are visable on the film edges.

  5. You have been misled. If negative film is overexposed, it turns dark.

    A quick test: Can you see the frame numbers on the edges of the film? If
    not, it's a processing fault. If you can see the numbers, but there's no
    image, the problem is probably in the camera.

    i am talking slides :)
    yes, frame numbers can be seen. so, i want to know what kind of
    camera fault can cause this kind of result ? you know, at least 7 stops
    of over-exposure needed to make the darkest part of slides turn to
    total transparent. how the camera make such a large exposure without a
    sense of myself ( operating in manual mode ) ?

    thanks.

    It was Satan. Satan did it.
    (I love these, "Guess what's wrong with my camera" games!)

  8. More information is needed:

    What camera?
    What lens?
    What conditions: Sunny, indoors, flash, nightime ...?
    What film?
    What shutter and f/stop?

    If the fault is in the camera I would suggest

    o A sticky shutter
    o Auto diaphragm doesn't close
    - lens not mounted correctly
    - camera mechanism
    - lens mechanism
    o Light meter, if followed when reading is in error
    - low battery
    - wrong ASA
    - busted

    Contax Arial
    Carl Zeiss 50mm/f1.4 Plannar
    outdoor, cloudy
    Kodak EB-3
    shutter: about 1/125 to 1/30
    apperture: about f4 to f8
    i can heare the sutter sounds clearly.
    why it did close when i take another roll? why it did not close only in
    the only roll?
    what part is possiblly the cause?
    it looks work well now.
    if light meter is wrong, i would get wrong shutter speed or f/stop.
    because i am aware of sunny-16 rule, so i can in the meantime detect
    such a big different.

    I'm sorry, but I have to butt in with another sarcastic point. If you think
    it's not you, then you must think it's the camera, and if it's the camera,
    all the amount of online speculation will never set you mind at ease, short
    of an easy solution, and obviously none is forthcoming. Send your blasted
    camera in for repair, or live with the doubt that the camera is faulty and
    may fail again at any moment. It's that simple.

  11. Well, if you insist that it _can't_ be the camera because everything
    works ok so then it must be the photographer.

    The way to the solution to the problem is not to throw up quick retorts
    but to carefully evaluate and experiment with possible causes,
    see if you can make it happen again.

    If the lens is not mounted correctly the auto-aperature mechanism
    will not engage.

  12. if it is a processing fault then the edge numbering may provide a clue. If
    it is the camera at fault with correct processing you should have clear
    normal looking edge numbers.

    i had a roll of Kodak EB-3 developed by a local lab. but the result is
    my guess is gross overexposure. if it happened in the first couple of
    frames, it is quite possible that you bumped the shutter or more likely the
    f/stop over to wide open. with slide film you really only need about 3
    stops to blow an image out.

    another possibility is that you had a sticky shutter, it just stayed open
    far too long, or a sticky aperture, can happen if the camera was very cold
    and took a while to warm up. OR. there was something loose, a screw or
    other debris that finally shook loose and could be gone now.

    Most likely the camera was set wrong for those first couple shots and then
    you changed something and set it right.

    hope it wasn't a clients' wedding

  14. If it is a processing fault the edge numbering could also be affected. A
    camera fault or exposure error with correct processing will still leave nice
    clear edge numbers.
