How to develop Ansco All Weather Pan?

    I came across a roll of Ansco All Weather Pan (620 Exp) in a camera
    destined for a yard sale. From the owner's comments, I'd guess that this
    roll of film dates to the 1950s. I've searched DejaNews and saw that I
    should use D-76 straight at 68 degrees F for 15 minutes. Does this sound
    about right? Do I need to try to compensate for fog by adding
    benzotriazole?

  2. Unfortunately, my Ansco info is too old to cover All
    Weather Pan. My memory is that this was Ansco's answer to
    Verichrome Pan and replaced Plenichrome, Ansco's ortho box
    camera film.
    Development will depend on whether you are trying to
    recover existing images or not. If not some Benzotriazole
    will help suppress age fog.
    However, if you are trying to develop the image any fog
    suppressant will tend to also destroy part of the latent
    image.
    Old film should be developed normally. Increased
    development will tend to develop the fog faster than the
    image.
    There are special techniques for recovering old images,
    using very active developers at very low temperatures, for
    instance, but I do not have specific instructions.
    Greg Miller of Film Rescue International
    http://www.filmrescue.com/ specializes in recovering images
    from old film. He is not cheap but if the images are
    potentially valuable its worth contacting him. He has said
    that roll film tends to survive longer than other types
    because its usually tightly rolled which tends to exclude
    air and attendant oxidation.
