    Is there a practical way to make a contact sheet using a flatbed

    The situation: I have most of my negatives in sleeved pages, and I
    thought it would be very useful to make a contact sheet of them. I
    laid the sheet in our flatbed scanner, scanned it, and converted to
    negative, but I didn't get anything usable. Is there a good way to do

    Can you provide a link to a sample of what you got?

    I can attach it to an email. I don't know of another way.

    Perhaps you knew this but, since I can't see a sample of the results
    you got....

    Since you're scanning negatives your scanner needs a transparency
    adapter (the top needs to shine light down through the negs) AND you
    need to look in your scanning software for the setting/button that
    sets it so the machine is scanning negatives.

    The contact sheet should be a positive. So I'm not certain what you
    did when you say you "converted to negative."

    One of the problems with doing it your way is that to have a useful
    contact sheet, you need to scan at a high resolution so that the
    individual frames are useful. That contact sheet page has a lot of
    "non-image" area (like the sprocket holes).

    Then there's your problem. Scanning negtives is the same as scanning
    slides. Both *require* a transparency adapter.

    Scanners generally have 3 basic media settings:
    1. There is one setting for scanning reflective artwork (photos,
    drawings, etc).

    Then there's two different settings for scanning transparent media
    2. One settings scans slides (positives)
    3. The other setting scans negatives, and when using this setting the
    scanner software automatically inverts the grey tones or colors so
    that the negative comes out positive. And note here that this setting
    can be used to scan both b&w and color negatives when used in
    combination with the color mode setting in the scanning software.

    Two psssible solutions for you are to 1. buy a transparency adapter
    for your model scanner OR 2. buy a dedicated slide scanner and get one
    that also does negatives (but these usually scan one frame at a time
    and the negative film needs to sit in a strip holder).

    1 - there doesn't seem to be one for our scanner, and the ones I found
    were very expensive ($450-$500)

    2 - I have a film scanner, but it would be too slow. It takes about 8
    minutes to scan a strip of 4 negatives, plus some time changing the
    film, etc. At 10 minutes per 4 negatives, that is an hour per
    24-exposure roll. And I've got about 150-200 rolls. (For the last
    couple of years I've been getting index prints back.)

  8. I've been experimenting with scanning a gray-scale negative on my scanner,
    for which there is no available transpaerency adaptor. Just putting the
    negative on the scanner doesn't work well. Putting a piece of glossy paper
    face-down over the negative helped a bit. My latest try is using a mirror
    face-down over the negative, and that looks promising. I scan into Paint
    Shop Pro, do an automatic contrast enhancement, then do a Negative Image to
    convert from negative to positive. So far, it looks promising, and
    certaintly good enough for a proof sheet.

    Another option is to pick up another scanner. I picked up an HP3570c for
    about 90 bucks and it came with the Transperancy Adapter.
