Yep. Ouch.

can't do it with anti-newton ring slide holders because the
anti-newton device results in an even more grainy result that looks
like the scanner was covered with sand when it was scanning.
<<<<<<<<<<<<

Make a mask (heavy paper or plastic) with a cutout the size of the frame
that sits on the lower (nearest the scanner lens) glass. Use anti-Newton
glass for the upper (nearest the scanner light source) glass.

The idea is that the scanner lens/CCD should be looking through either clear
glass or no glass, and the anti-Newton glass should press the film onto a
4-sided frame. This won't work for perversely warped frames, but will be
fine for most.

The anti-Newton glass holder for my scanner (Nikon 8000) only has
anti-Newton on the top glass. They think that the unevenness in the film
emulsion should prevent Newton rings most of the time. Wrong. But they knew
they were wrong and provide masks<g>. (Actually, I cut my own masks because
the masks they provide only mask one frame.)
