Silverfast vs Espon vs Vuescan

  1. I have a V750 and am familiar with the Epson Scan utility, which is quite good, except that it cannot do multiple scans. OTOH, I hate Silverfast interface and commercial policies (I refuse to pay them $70 for an upgrade from 6.6 to 8) and having purchased the Pro version of Vuescan ages ago, that's what I use. Learning curve is not really intuitive but it's not rocket science either. I you could learn Photoshop, it's a piece of cake. BTW, I've managed multiple scan passes with Epson Scan just by doing three different scans with different exposure settings and then blend in Photoshop.
     
  2. Does the V750 change the scanner light intensity? Doesn't it scan at maximum so that you'll get the max out of your shadow areas during a normal single scan? The scanner should not clip the highlights.
    My V600 scanner picks up the full black to full white data of a picture in a single scan. Of course, I have to adjust the black and white points afterwards in post editing. But there's no additional data I could get from doing multiple scans.
     
  3. I run an Epson V850, and use VueScan 64bit, SilverFast 64bit, and EPSON Scan. All three have assets and drawbacks, and over time I've chosen the software that fits the film. I run Win 10 on a Dell desktop and the scanner is cabled to it.

    I don't think that any of the scanning software packages are a "do it all". There are just too many algorithms out there for Fujicolor, Fujichrome, Kodachrome, Kodacolor, ad infinitum.
     
  4. - Are you talking about negatives or slides though Alan?

    A properly exposed and developed B&W negative shouldn't much exceed a density range of 2.2, which most scanners can easily cope with. OTOH an unfaded slide can exceed a density range of 3.5 and make the best of scanners struggle to dig out the deepest shadow detail. It's this latter case where multi-pass scanning comes into its own.

    The low density range of negatives brings its own issues. A 2.2D range is only a brightness ratio of about 158:1, less than 8 bits in digital terms. So the scanner's 16 bit A/D is effectively curtailed to a meagre 7.5 bits. After reversal and tone curve adjustment, this can easily result in posterisation (visible tone stepping).

    Ah, the joys of scanning film!
