Storage of 35mm slides - long term

    I'm in the process of scanning the slides my parents accumulated over
    the coarse of their marriage and throughout my childhood. They've
    always been stored in boxes meant for slides, two plastic ones and a
    metal one. The oldest ones are from 1950. All seem to be in excellent
    shape despite being stored in who knows what kind of temperatures over
    the years.

    Once I've converted all the slides to digital what is the best way to
    store them? I want to keep the originals in as good condition as
    possible - of course.

    I don't know if they're still in such good shape due to dumb luck, or if
    they're just sturdier than I would have thought.

    Any and all suggestions are appreciated!!

    How I wish I could preserve the sounds of the old projector, the sound
    of putting up the projector screen and its smell. Ahh... memories. (-:

    B-
    I would suggest that you digitize all and make them (dig) your
    archive.

    Reason: (1) Dyes are ephemeral and decay with time. The three color
    layers do not do this equally, so there are also color shifts in
    addition to loss of saturation as time goes by.

    (2) Not apparent: Dye layers in film are actually hard gels. That
    means they are thick liquids, like glass. As glass in old (OLD!)
    windows settles to the bottom, the dyes in old fims diffuse into their
    base matrix with time, resulting in loss of detail.

    (3) Unproven: As the gel layers dry out, it is possible that the
    granulation of the original film will increase, with more loss of
    detail. I know of no research that has confirmed this, but if true,
    would mean that older film would have more grainy images with less
    detail.

    There's more, like deformation of the film base what would ruin the
    images.

    For us, I would suggest a fine archival scan, duplicated and kept in
    accordance with the practices of professional archivists and records
    keepers.

    For your originals, I can only suggest they should be kept in a low
    humidity environment, cool, and away from light. Do not allow them to
    come in contact with wierd plastics that could bleach or otherwise
    transform the colors.

    You can email me directly for more info, should you choose.

    Hi,

    I lost many, many beautiful and memorable color slides due to fungus
    invasion of the gel layer, despite careful preservation with a
    dehumidifier, etc..

    Do digitize the slides to the best quality possible, then burn CD-Rs
    using the best blank discs = Taiyo Yuden, made in Japan, with the
    cyanine dye giving a blue-green appearance to the back of the disc.They
    can be obtained in a 100-pack on a spindle for 32 cents each. Then you
    can use one set, and put a duplicate set into a safe and
    climate-controlled place. In addition, every 10 years or so, burn new
    copies of the discs. These greenish discs should last 100 years, but who
    knows.

    Good luck.

    Be aware that Kodachromes (which are archivaly the best as slides) are
    notoriously difficult to scan and do not scan with Digital ICE at all
    or at least not well.

    Almost every slide I have is a Kodachrome. The only exceptions are the
    very few slides my parents bought while in Paris in the mid 1960s.

    The very oldest ones (parent's honeymoon) are in a graying/beige jacket
    with a solid red border on all four sides. They say, "Kodachrome
    Transparency. Processed by Kodak." The newer ones (mid 60s and on..)
    have white jackets with the same lettering in red and a yellow corner.

    My scanner is an Epson Perfection V300 Photo. Nowhere near the top of
    the line, but it does have an adapter for slides and negatives. That's
    why I bought it. So far I'm very pleased at the condition of the slides
    (as mentioned earlier they've been stored in slide boxes and have been
    moved at least 8 times over the years. They've always been kept in our
    living space (no freezing or hotter than hell storage areas), but beyond
    that no special care has been given them. That's why I'm so pleased at
    their almost perfect condition.

    The scans are also coming out very well. Only a very few show any signs
    of fading, other than that they look like they were taken yesterday. I
    wish I could have done this while Mom was still alive; there are quite a
    few people and places that are not part of my memory. Still, I'm
    scanning them all!

    I appreciate any and all comments.

    Merry Christmas! Happy Hanukkah! Joyous Kwanza! Festive Festivus!

    Hi,

    There is a camera shop in my area of N.Y. State that uses a very large
    Japanese-made scanner. The Kodachrome slides that were scanned on it
    made excellent digital images on a PC screen and when printed out.

    Actually, Kodachromes scan quite well with D-Ice.
    BUT, one has to use the latest version of Nikon scanners - V ED, 5000ED, 9000ED
    to get it right. I haven't got the slightest problem with my 9000 and V ED.
    No, the 4000 and the 8000 are NOT the latest version, and they indeed are lousy
    at doing Kodachrome.
    Don't get me started on the Minoltas and flatbeds...
