    Question About Picture Glass and The Epson V800 Scanner

    When scanning my 4x5 negatives, I like to place them on the Epson Fluid Mount Holder and place a piece of Picture Anti-Reflectant glass on top of the negative to keep the negative perfectly flat.

    I always place the emulsion side down so it faces the scanner optics and then place the glass on top of the negative, etched side down.

    I have read that Anti-Newton Ring glass is the suggested method but its pretty hard to find here in the UK and I am wondering if using this picture anti-refectant glass is compromising the scan by not using Anti-Newton ring glass.

    Not sure what the difference is to be honest.

    There is very little difference between the two.

    Also, is AN glass necessary if you're wet mounting? Instead of glass on top, I use Aztek scanner overlay film and never have rings with the wet mount process. Though I guess you didn't actually say you were wet mounting.... ???

    Wet mounting is so simple and quick I totally recommend it. I actually timed it and mounting a 4 x 5 took all of 23 seconds.

    Initially, I just dry scan to get a feel of the overall exposure and development. If the photograph is for a sale or going out to print, then I will wet scan

    Some matte picture glass may have a relatively coarse structure that can end up within the depth of field of the sensor array of the scanner, resulting in artifacts across the entire image area and/degradation of fine details. If you don't experience these issues, then there's obviously no reason to revise your workflow.
