    I need to scan about 3,000 color slides from my grandfather's collection to
    a CD for his viewing enjoyment without the hassle of setting up a projector.
    I will also need to do a digital capture from his fifty or so 400' reels of
    8 and super 8 films but that's another issue.

    I bought a Konica Minolta Dimage Scan Dual IV that does batch scans of 4 at
    a time. Of course I am scanning at the highest possible dpi resolution with
    all the 'auto-correction' tools turned on so that we will have the very best
    archive of these slides.

    Some questions:

    1) what is the best way to clean a slide other than using a can of air? I
    mean, that will get the dust and the software cleans up the rest but what
    about those slides with finger prints and stuff on them?

    2) When I try to use the 16bit color depth option, the JPEG format is not
    available to save the scans. This unit only supports TIFF files at 16bit so
    is the sacrifice of going to 8bit worth the time needed to convert the final
    scan into JPG format? Note: I plan to use NO compression, scan at the
    highest dpi and use the all the options for the Auto Dust Brush, Color
    Matching, etc. keep in mind that there are about 3,000 of these so - is the
    16bit color option in TIFF format worth the trouble to go back and convert
    them all to JPG format? Do I gain a TON of quality? Should I be using TIFF

    3) Is Anyone else using this Dimage IV model and having trouble with Windows
    XP? I seem to keep getting an 'error = 1 . unknown error' message on my XP
    PC but the Windows Me works fine. I really want to scan this to my media
    system with the XP Pro on it. Else, I will need to transfer everything over
    the 'net or via CD from the Me to the XP 'puter.

    Well, you appear to be so far off the beam that I wondered if your post
    was a troll. However, here are some quick answers.

    If you scan a slide at max resolution and 16-bits, saving it as a tiff,
    then *each* slide will result in a file of about 30 to 50 megabytes,
    depending on your scan dpi.

    Even at the lower figure of 30MB, that's *90 Gigabytes* of storage
    required. You will get about 23 images on a 700MB CD. That means, for
    3,000 slides, over 130 CDs.

    Scanning at 4,000 dpi and 16 bit is *massive* overkill for anything but
    large high-quality printing. I presume you are intending to display the
    images via a TV. If so, a 1,000 dpi jpeg image at a compressed file
    size of about 150 or 200 kB is all you will need, perhaps even less. At
    that size you will get all 3,000 images on one CD, and 8-bit depth is
    all you will see on a TV. Bear in mind a TV will show a maximum of about
    500 lines, so at 1,000 dpi you are providing twice the resolution that a
    TV can display.

    I suggest you scan several images, say 10 or so, save them as tiff for
    reference, then progressively downsize and save as jpegs at varying
    dpi's and compressions. Burn them to a CD and then view them on
    whatever you will be using for a display. You will then be able to pick
    the minimum file size that will yield adequate quality.

    If you carry on doing what you propose, cleaning, scanning and afterwork
    on each slide I estimate it will take you an average of 5 to 10 minutes
    per slide. For 3,000 slides, that's 250 to 500 hours of work, or about
    an hour a day every day for up to two years.

    Better have a rethink,

    Colin D.

    4 at a time is not a batch.
    Get something called Ilford Antistaticum (a cloth, about $4.00).
    Lay the slides on it. Fold the cloth over the slides smooth the
    cloth into the slides.
    Unfold the cloth and then use a very soft brush (I use Kodak
    Camel hair 1").
    That's it. Sometimes I add a quick blast from a can on each side.
    (With canned air:
    -always do a cleaning blast (1 sec) away fromt he work area.
    -always hold the can so the nozzle is horizontal.

    To archive, TIF is best as you have all the data for later uses
    from printing to web pages to cropping out detail etc. It takes
    gobs of room so 3,000 slides will require a lot of storage
    (DVD's, CD's...) You are not going to get 3000 TIF's onto a
    CD... 3000 JPG's at moderate size and quality, perhaps.

    For printing and monitor viewing, 8 bits is usually more than enough.

    Go to the Minolta site and download the latest V's of software.

    Colin -

    Thanks for the heads up on the file size!

    Although I intended to save the whole archived project on a 250GB HD, I sure
    don't want to burn 130 CDs. Maybe DVDs instead at only 20 of them.

    Thanks again!

    Thanks for the info on the cloth.

    I know the TIFF format is huge but I intend to archive the whole project to
    a 250GB hard drive along with some other pics. For playback, I think I will
    burn to DVDs at only about 20 of them instead of CDs.

    The scans look great on my 61" Sony TV.

    1iJack, Aug 30, 2004
  6. I have to agree with Colin, I think you are far overkill. Do some test
    at reduced resolution and with compression. See if you can tell the
    difference on you 60" TV.

    Do a "Best of the Best" Pick the best 50 and scan them at the higher

    I also suggest that you make two archival copies (CD or DVD) and store
    one and give you father the other. That way when the HD crashes (which it
    will) you will likely still have one copy. because the other one will have
    been damaged or lost.

    It's not huge if you want to make big prints from them, and you may want to
    do just that down the road. This will prevent you from having to scan
    twice. Also, if you're using Photoshop CS, you will get a superior non-full
    resolution image by scanning full rez, and then downsampling using the
    Bicubic Sharper algorithm (one of the options in Image Size). Superior to
    simply scanning at a lower resolution/file size.

    As far as cleaning the slides go, if you didn't buy a scanner with Digital
    ICE, you made a mistake. It saves 20 minutes of cleanup on my average
    slide. If you still have many thousands of slides to go, consider
    purchasing a film scanner with Digital ICE. In addition to Digital ICE,
    many Nikon scanners have a slide feeder available, allowing you to batch
    scan 50 slides at a go.

    I'm doing the same thing - scanning my deceased grandfather's slides
    so that the rest of the family can enjoy them.

    I'm using a Nikon Coolscan 4000 with the slide feeder. Indeed,
    resolution is always a comprimise. I wanted to choose something that
    would be good enough to view on a TV, as the final method of
    distribution to the family will be on DVD. They're organized well
    enough so that of somebody wants a "really good" copy, I can drag the
    slide out and scan it again at 4000dpi. That being said, I'm scanning
    them at 2400dpi, and saving using JPEG. I know, not a great archival
    choice, but for what I'm doing, it'll be good enough. It saves on
    disc space, and it's easy to backup to DVD-R/W every once in a while.

    I use mostly canned dry air, but I also have Digital ICE3 available on
    the scanner. Those old Kodachromes can be a pain, but it's amazing
    how beautiful they look considering some were shot in the mid 50s.

  12. quite a big job with your selected equipment:)
    not an perfect decision
    I use the cleaning paper for glasses
    I use vuescan, save all images as jpg wth quality set to 75. This results on
    file size from 800KB to 1.5MB
    I use a Nikon LS-2000 with SF-200 sucessfull with Windows 95/98/NT4/2000/XP
    Of course I didn't use Windows ME and did not check on Windows Server 2003
    your welcome

  13. Agreed
    I did and am still doing the family photos over the last 50 years.
    I had many thousands of slides on many types of film. Bout a 50:50
    mix of Kodachrome and Ektachrome. Maybe another 3000 that were Fuji,
    but still E-6. I used the Nikon LS5000-ED with the SF-210 slide
    Canned air, sometimes a photoflo solution and care, sometimes the
    paper as Wolfgang has done. Oh, and a lot of luck and a scanner that
    uses Digital ICE which works great on E-6 and not worth a darn on
    Lord! I scan at 4000 dpi and save as TIFFs. Files are about 50 to 60
    megs each.
    With the LS5000-ED and SF-210 XP Pro (SP-1 or SP-2) works just fine
    using either Nikon Scan4, or VueScan.
    No compatibility problems

    BTW, I've been working on this project since last February. The last
    notebook of negatives took 80Gig of storage and I only have two more
    notebooks full of negatives to go. THEN I have something on the order
    of 200# worth of very old prints to scan on the flat bed.

    I'd have to count, but I think I have used 64 DVDs for archiving.
    That is almost 300 Gig and as I said, I have nearly another 160 to go
    before starting on the old prints.
