    Thanks for your input J. I've thought of this, but didn't really
    expect to get the resolution I need if I used a standard Digital
    Camera whose CCD is designed for color imaging.

     A dedicated greyscale scanner would be best, I know HP has a high
    res color model that has a backlight assembly, but don't know anyone
    who's used it - it would be about an $800 experiment. I'll pay that,
    if I can be reasonably certain of the outcome.

    But now that you mention it I do have a couple of high end (12-bit and
    16-bit) B&W CCD cameras that I might try with something similar to
    what you suggest. Now to dig around for a suitable imaging lense...

    Any others with thoughts or suggestions?

    Thanks again.
