    Thanks OP for the rundown. I wondered if there was a way to adjust for sharpness in scans. Too bad they can't do it in the software.

    Is Silverfast sharpening the scans automatically? That may account for why they all look pretty similar. Is there a way to shut sharpening off?

    I scan at 6400dpi then do a 2x2 bin to 3200dpi to save as 48 bit rgb save negatives as linear raw tiff and positive film as positive.

    I also wet mount using betterscanning kit. You will see biggest difference in wet mounting and a big dig difference in dpi setting. 2400 is to soft for me. If I could I would save all files scanned at 6400 dpi, but they have not finished big tiff format so that is iffy, plus files are big. Which is why I bin them.

    I use Vuescan for everything.

    On my drum scanner I scan and save at 4000dpi. Checking focus and aperture for each image
    . File sizes are similar, but quality is greater than Epson.

    I get the argument about max this and max that and no better than this or thst, but I have done actual testing and posted results finding that 6400 was indeed the best and settled on less, like 6000 till I discovered the 2x2 bin function afforded in Vuescan.

    The above works for me hands down. Hour methods and mileage may vary.

    I Al's believe in better to have as much info and not need it, than to need it and not have it.

    Steven: How do you do your 2x2 bin from 6400 to 3200?

    70% of that explanation sounds like science to me. :-)

    It creates a "super" pixel by combiningb4 pixels into one. The final image then is reduced from 6400ppi to 3200ppi with resulting 3200ppi image having better everything than if scanned at 3200poi.

    If you prefer 2400ppi for example, scan at 4800ppi and 2x2 bin. Final image will be much better than a native 2400ppi scan.

    Also, Vuescan us only scan software I know that has thar feature.

    What method do you use to reduce it from 4800 to 2400?
