    I don't believe that the 850 comes anywhere close to 6400 DPI. I've seen several comparison tests using the USAF target that concluded that it is basically the same as the 750 - ie around 2400 PPI.

    Yeah, not surprising... it is a flat bed and they tend to exaggerate their abilities.

    Depends on the flatbed. Some actually meet their own specs, but they tend to weigh a hundred pounds or so.

    thanks
    As others have mentioned, you can calculate based on how large you intend to print. Since you are scanning for display on screens only, the highest resolution commonly used screen is Apple's 2880 1800 display. Let's say you want to display a landscape oriented image at the largest possible size on that screen. So the long side of your final file would be 2880 pixels. 2880 4.67″ is ≅ 617. That's the PPI you would have to scan to.

    Personally, I think that's overkill, but OTOH, if you ever want to print these, there's no such thing as scanning too large. I scan at 4800dpi and then reduce to 2400dpi. Here are my Vuescan settings. Just export them as whatever name you like but the file name should end in .ini; then import in Vuescan:

    Agree that Ken's tutorial is very good for black and white negatives.
