Overexposure problem

Discussion in 'Photography' started by Thomas T. Veldhouse, May 10, 2005.

  1. I recently aquired a used N80. The camera appears to be in great
    condition. I put a roll of Kodak 100UC in it that I had around (expires
    June 2006) in the refridgerator. Well, out of 36 pictures taken, about
    30 of them were extremely over exposed. Many of the over exposed
    pictures were in backlit scenes about 1 hour before sunset and in a
    couple of cases it was a front lit scene near the edge of the
    Mississippi. Most of the normally exposed pictures were the first I
    took, but a couple of them were in the middle of my shots of the river
    with the front lighting and backlighting near the edge of the
    Mississippi.

    What is the most likely cause of the overexposure? I let the meter do
    its work in either Apeture priority or Shutter priority mode. I took a
    picture of a tree full of white flowers as a test and set the
    compensation to +1eV and that picture turned out fine. I am afraid
    something might be wrong with the shutter, as if it is sticking some of
    the time. I wonder if it is possible that it was the film. I had the
    film developed at Walgreen's as it was a convenient way to check my
    results (I wouldn't normally waste a good roll of film on Walgreen's).

    Thoughts?

    You already had it...shutter.

  3. Any idea what it costs to get that fixed? The shutter looks to be in
    good shape; it is not obviously dented or damaged.

    Thanks!

  4. Ask a camera shop that sells Nikon. They should know. A new N80 can be found
    online for less than $300, so I wouldn't spend too much on the shutter. Do
    you have any recourse as far as getting the seller to take it back or go
    halfers on repair? I'll bet the seller knew and didn't say, the rat.

    It's very possible you have it in spot metering mode, since you're
    describing problems in scenes with wildly light/dark areas. If the
    selected spot is on a dark area, it'll try to expose for that.

    There is a program mode setting to reset to factory defaults, after
    which you need only check that the external knobs are set properly. I'd
    start there, and progress from an evenly lit scene to ones with wide
    variations. You could also watch the shutter speed and aperature values
    in the viewfinder to see if they suddenly skew oddly.

    Perhaps, try shooting the same scene with different aperatures and see
    if the varying shutter speed makes any difference. Or see if the same
    photo shot 12x comes out different between frames, despite identical
    settings.

  6. I am retesting with a second roll of film. If that gives me trouble, I
    will have to get it fixed. Then I will hit up the seller (I already
    gave positive feedback). I suspect the guy just wasn't using it very
    much, so perhaps when a little of the lubricants get moving ...

    BTW .. no sign of mold either.

  7. I have tried it with both spot and 3D Matrix. I am quite familiar with
    the Nikon camera, as I shoot a D70 much of the time.
    It turns out I did have some of the custom settings set for the exposure
    locking, including the option to lock when the shutter button was
    half-pressed. Perhaps this was an issue? I reset all custom settings
    to default other than the grid display, as I like that in the
    viewfinder. I will see how this goes after the second roll of film
    (cheap film this time).
    Several of the photos that I took were bracketted with +- 0.5eV. I also
    was shooting a lot of the shots at F5.6, F8 and F11. There didn't seem
    to be a consistant pattern. I really hope what I mention above is the
    cause.

  8. Well ... it turns out it wasn't a problem with the camera. The next
    roll of film (Kodak Gold 200 ... cheap from Target) worked out just
    fine. I took pictures of everything and tried all appeture stops and shutter
    speeds and it worked in all cases. So, the problem must have either
    been the roll of film or the Walgreen's development. I don't know
    whether to suspect the former or the latter; and now I don't know if I
    can trust the remaining two rolls of Kodak Ultra Color 100.

    It's sounds like a badly stored film, trash it and go out and buy some from
    a professional store, it's cheaper in the long run and you will know for
    sure.

    Indeed possible.

    Other possible causes:

    1) Sticky/sluggy shutter from not being used in a long time? - now
    self-healed through exercise on the first roll.

    2) Battery issues (colder when you shot your first roll vs warmer now)
    ? I had (actually, still got it somewhere) a Minolta who's idea of a
    flat battery indicator was to shoot the last roll over-exposed.

    3) Walgreens screwed you over! <- I place my bets here.

    4) Global dimming. The world is darker this week and it shows in your
    photos.

  11. That was my thought as well; bad film. However, I did buy it from a
    great store in Downtown Minneapolis, National Camera Exchange. They
    took it from a refridgerator and I brought it home and put it in ours
    until I used it (I let it worm before loading it into the camera).

    Oh well, I would rather lose the film than take shots and lose the shots
    and the development costs as well.

  12. Hope not, but healing is healing ;-)
    Seems full power ... same basic conditions in both cases.
    That is possible ... the woman was a fool. She might have done
    something.
    While I don't deny that Global Dimming exists (it seems mostly a problem
    inside my head than outside ;-), I think the problem is overexposure ...
    thus washed out lighter pictures ...

    Still could have been the shutter...sticky from non-use, use it, now not
    sticky.

    Actually, to be a bit of a bore, it's true.

  15. When this happened to me, it was shots over f5.6. The iris in the lens was
    sticking so that it didn't stop down fast enough so it was still wide open
    when the shutter fired.

  16. I don't think so in my case, as I used two different lenses while taking
    shots on that roll of film.
