My understanding of Newton Rings is that they came from the same source as the rainbow on an oil-slick or a thin prism put on a reflector. Namely you are getting 1/2 wave interference patterns from the light reflected at each boundary layer - a boundary layer is where the optical density, (or

It is a powder lightly dusted on the glass surface of the scanner to prevent film-to-glass contact. The film-to-glass contact is what causes the Newton Rings. Maris - Original Message - From: SKID Photography [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, August 29, 2001 9:37
