    What caused this "half moon dot" in the attached photo?

    We were visiting family and my wife wanted a photo of the church where her parents had gotten married.
    Strange white anomaly on the roof. Any ideas?

    Cute church! That looks like an apparition to me... specifically a white dove.

    Had you not been shooting stills you'd really know that's what it is!

    This occurred in order to give you practice in spotting prints.

    Does it show on the negative or just the print?

    Maybe something in this thread can help
    http://www.largeformatphotography.in...pots-on-prints

    or this one

    If it's on the negative, then it's either a stray light source or something interfering with the film development and leaving a dark spot. i doubt it's a light source since it's clearly defined with sharp edges as you point out and a bellows pinhole would be likely be larger and more diffuse. I guess you could always get a defective film negative but that what are the odds of that?

    I see on the Flickr site, you're using the new SP-445 tank - any chance something might have been touching against the negative and preventing the chemistry from working?
