    Actually, the EXIF data shows that your settings were not the same in both
    photos. For photo #1, the aperture was set for f 4.5, and your metering
    mode was set for "pattern."

    In image #2, your aperture was set for f 3.5, and your metering mode was set
    for "center weighted."

    Still, I don't think that your second image should be so totally over
    exposed, but you might try some more controlled shots to see if you really
    have a problem.

    i have a nikon D50.
    but the pictures keep on getting washed out.
    i have taken two pictures "one taken straight after the other using the same
    settings, and of the same item from the same angle.
    the washed out one was the second picture taken.
    am i doing something wrong?

    the first picture is here

    the second one is here

    The camera was set to "AUTO" this is why i wondered if there may be a fault. the pictures were taken one straight after the other. camera was not moved in between shots.
    i have had this before, but normally i use Manual settings for most of my shots.

    That's really odd that the camera would make so many changes between the two
    images. Even the ISO changed. The first images was 1/80, f/4.5, ISO 400.
    The second one was 1/13, f/3.5, ISO 800. I'm not a Nikon user. Does the
    camera control ISO in auto mode too?

  5. So why are the crops different?? According to the EXIF data, you
    *also* changed the metering mode, but that wouldn't cause such
    over-exposure. The exposure program mode is listed as '0', which is
    not defined in the EXIF specs - it depends on the camera. So I can't
    tell if it was on Auto or not.

    You need to check again a little more carefully, document what you did,
    and if that really was what the camera chose on Auto.. take it back.

    thats what i dont understand myself.
    the first picture seemed ok. the 2nd and 3rd were washed the 4th 5th 6th was fine again.

    just looked through all of the data again and i think i may see a pattern in the washout.
    all of the pictures have a different f/#
    but the main differance seems to be in the metrering mode.
    the good pictures have "metering mode" set to "centre weighted average"
    but the clearer pictures metering mode is set to "Pattern"

    i will take some more later today and manualy change the metering, to see if it replicates the problem.

    I was going to suggest checking to see if exposure bracketing was turned on,
    but that wouldn't cause these problems. Something is really whacked out on
    this camera. Time for a trip back to Nikon I think.

    since the lastpost that I done,
    I have opened the pictures in "Nikon capture editor" and I noticed that both of the washed out pictures are taken at ISO-800 and the others at ISO-400.
    I have since gone into the menus of the camera and changed the "iso control" off then the "iso Auto" off, I then went into the "ISO" and changed it from 1600 to 400,

    im not so sure that the camera is at fault but more likely that some settings were changed at some point.

    I must get used to using "Nikon captor editor" more, as that shows more info about the pictures.

    I will go out again today (suns out nicely) and take some more shots to see if it was the settings

    It would probably be a good idea not to have too many "auto" functions on
    all of the time. Mostly, I have everything set manually, and use only auto
    focus, and either Aperture priority or shutter priority (I set my exposure
    composition to -.7 most of the time, to keep from clipping my high lights).

    I guess I'm still a bit lazy - I should do more manual settings than that.

    As stated above, make a series of controlled test shots over a few days,
    then have the camera evaluated, with the test shots as samples.
