    Do dust spots become more apparent as a print dries? [RC paper]. Thx.

    I swear that there was nothing on a print a did last night....then in the
    morning those tiny white dots showed up. The dust fairy perhaps?

    I don't think so, but if your viewing light is different, that would
    certainly explain it.

    At least I think they're dust spots. Now I'm wondering maybe my water is
    questionable. Sticking with the dust spot theory for a moment. I was
    thinking that as the print dries -- the shrinking geletin started to "pull"
    open any small spots which are invisible when the print is wet. Does this
    happen?

  5. Are the spots consistently white or shall we say are they fuzzy at the
    edges and white from edge to center? or are they white with a darker
    middle?

    Spots that are slightly white at the edge and darker in the center
    that are more or less round are typically air bells that got trapped
    under the paper during the initial first 20-30 seconds of development.
    It could be that your not agitating enough to dispel them.

    I would also check your negatives for corresponding imperfections.

    The last thing to check is if you prints are too wet when starting the
    drying, squeegeeing or blotting should eliminate it: if that is the
    cause.

    No just opposite should happen: if that was a factor (which its not) -
    the relative size of a prints surface shrinks when dry. As opposed to
    wet in a tray.
