[filmscanners] Re: Newton rings

["HPA" <tom@historicphotoarchive.com>]

Many manufacturers of glass slide mounts make anti-newton ring glass.  If
you can get a few sample slide mounts, that is all you need.  Gepe is a good
brand.

These work well in the Polaroid scanners.

If you are familiar with a focomat enlarger, try to duplicate what they are
doing.  Otherwise, try using one sheet on top of the tranny only.  This
gives an excellent result, without having to use glass below the image.

The Leitz focomat anti-newton adapter for my enlarger cost $150, so I
consider all this stuff for scanners to be a bargain.  The anti-newton glass
from a slide mount will pay for itself in five minutes.  If you want another
film holder to make special modifications, it too will pay for itself in a
matter of minutes.
