    Your observations tally with our own Nathan Potter's analysis. See his graph, which shows that usable contrast drops below 50% once we exceed 1500 dpi.

    One can make the case that the scanner produces higher resolution data - and indeed the chart shows scanning data at resolution up to 2500 dpi - but contrast diminishes accordingly.

    What moderately priced flatbed scanner do you recommend?
    Thanks
    Microtek i900 or its replacement scan the negatives w/o glass between the negative and the scanner light.

    Based on many threads, when dry mounting, it seems the number emulsion side down folks = the number of emulsion side up folks.

    Me, I'm a card-carrying member of the emulsion side down party.

    Either way, the key point is that you're putting the film (emulsion side up or down) against the etched (AN) surface of the mounting glass.

    You’re mistaken. Vuescan ships with it’s own drivers for a lot of scanners (not all).

    This is how they support lots of scanners on Linux (I use my V750 under Linux). And also how they can support the Nikon CoolScans under 64-bit Windows (which is why I purchased VueScan to begin with).


    My father taught me emulsion-side-down for contact prints and for enlargers. So I’m in that camp also. But now the Epson V7X0 holders show clearly that the mirror image should face up, i.e., emulsion side up. The native raw data the scanner delivers is also mirrored if emulsion side is down. They even explained this in the manual of the old Expression 1680.

    But now for the V8X0, suddenly they have instructions to put the matte side down and the shiny side up.

    you might get lucky with a epson 4870

    A duh, moment. I transferred all apps and data to the new system some time ago, including Vuescan, but it never worked, thinking it was a driver issue. The real problem was not having the 64 bit version of Vuescan. Problem solved, thanks.

    I agree; in case you use glass, of course. I use the Epson 4990 stock holder which is glassless itself and suspends the film above the platen, resulting in the film not touching any glass. I understand wet mounting could show an improvement, but I haven't tried that approach yet.

    I was given a HP 4890 and it's my only way of scanning 4x5 negs. Unfortunately it doesn't do a very good job, as I've since found confirmed by some reviews. I'm wondering if this is basically a cheap hardware issue, or could good software like Vuescan make a difference. Thanks.
