    Epson V750 native resolution

    Hi

    I have just purchased a new Epson V750 and plan to scan 4x5 vlevia, what is the best and native resolution of this scanner without interpolation.

    The manufacturer claims a max optical of 6400spi. You'll need to scan in two pieces for color with 4x5 at that resolution, resize them to 3200 and join them in Photoshop. The best results are wet mounted IMO. Lots of threads about various approaches.

    By scanning a 35mm microfilm target to test the optical limitation of the scanner I decided to scan at home at 2400ppi on the V700. I also tested quite a few of these and the numbers varied based on the scanner from as low as ~2100 to as high as ~2500 in our lab.

    Focusing the beast is a black art. Many never get it focused AFAIKT. Have fun.

    Jeremy, are you referring to the true resolution (as often referenced by Sandy) or an actual scanner setting?

    I find it necessary to use the beast's ;-) max optical setting (6400spi) and wet mount to achieve the best true resolution.

    Try the Silverfast website. There is a special Epson Scanner section.

    Hi looked every where, whilst you could scan at 12800, there must be an optical resolution, I have read 1600 and other places 2400, not sure which one or is somewhere in between, as I want to scan at he larges with most optimum resolution possible.

    I'm no expert, but I have consistently read that people who test the recent batch Epson scanners get somewhere around 2000 spi, plus or minus a few hundred, and my experience seems to bear this out. Higher settings just seem to produce larger files, but do not result in additional, usable visual data.

    I set my Epson 4990 to 2400 spi. For additional detail, I shoot 5x7 instead of 4x5. It's cheaper than getting a high-end scanner, and you can make (albeit small) contact prints if you like.

    The top prosumer flatbeds top out at around 2400 ppi. You can scan at higher resolutions, but all you'll be getting is interpolation. One easy way to test is to make a series of scans (1800ppi, 1900ppi, 2000ppi, etc) of a flat detailed object (not film) and examine each scan for crisp detail. At some point, you'll see that the scans get bigger, but start getting softer. Since an actual object has an infinite amount of detail, the limiting factor won't be the resolution or sharpness of a piece of film.
