What DPI scan = paper print?

    So I want to scan some precious family photos from the 30s up to the
    2000s.

    I would like to preserve all the detail that is in the original print,
    in the scan.

    Question is, at what DPI should I scan these prints so as to preserve
    all the detail in the precious, irreplaceable original pix?

    Are there different answers for the old b/w prints versus the modern
    color ones?

    If I could just get the DPI estimates, I can read up on line pairs and
    granules separately on my own. Right now I'm just curious if anyone
    knows what the DPIs should be?

  2. 300ppi *at actual output size" is fine for any type printing, short of
    transferring to film.
    Many Epson folks swear that only 240ppi is necessary.
    Run your own experiments.

    Good ppi/size calculator at Waynes:
    www.scantips.com
    Which helps determine actual ppi necessary at 1:1 scanning for the
    intended output size.

    Or you can just always scan at highest optical rez of your scanner and
    scale down in image editor if you don't want to do the math.

    Thanks for the tip! Useful. I'll return with a tip of my own. I used
    to munge my email addr like you, before the AT sign. Until someone
    pointed out to me that still made the domain valid, so the domain was
    still being hammered with spam attempts. You could consider munging the
    email address AFTER the AT sign, so that the spammer's attempt will
    never bother anyone.

  4. Just tried it again:
    "553 553 sorry, your envelope sender domain must exist (#5.7.1)"
    As a matter of fact, it won't even POST without valid email domain in
    setup. Go figger.

    300-400 DPI is ideal.
