    Isn't the problem with an 8x10 neg carrier for a scanner that the film sags? If the film is supported with glass or plexiglass there are problems with Newton rings and glare etc . . . am I wrong?

    There are only three types of mounting flanges; too big, too small and wrong thread!

    If the film is laid emulsion side down and a sheet of Anti-Newton Ring Glass is laid on top the problems seem to go away. Of course afterwards the image has to be flipped horizontally to make it the right way round.

    Both great links. The second I have been following for a while. They have made some progress since I last checked in.

    The first link is also good and I have my variation which some have called 'bad idea'. Instead of hovering an 8x10 1.5mm over the V700 glass plate, o found by empirical testing that my V700 gave best results with my very old AN glass laying on the platen and my negative laying on that, dead flat, emulsion down. Taped only if necessary. With the 8X10 film guide in place. So my film is about 1.5mm above the platen and my scans looked best done this way. To me, which is all I care about...Logic be damned. I did try it many other different ways. Some say these V700's are all different from factory spec 'stack up' issues that make them inconsistent unit to unit. So each owner/user must find their best method.

    The suggestion of a 1.5mm film frame used in place of the film area guide is similar to the good results I get with my homemade 5x7 matboard negative carrier, which fits just inside of the film area guide thingie.

    The other potential option for this is to create an 8x10 holder that allows partial scanning of the image using the high-res lens and then stitch the image. I can't recall the exact scanning area of the high-res lens; however, I think that it's around 5x7". If you had an 8x10 holder that has a 5x4 opening, then the remaining 5x4 area would be supported to minimise slumping.

    I looked at this idea for 7x17" scanning in this thread.

    Surely you would need to scan the 8x10 four times if working on 4x5 portions?
