One would be to replace the glass with anti-newtonian rings glass if it is not already that. Another would be to use an anti-newtonian ring powder on the glass between the negative and the glass. I suppose you could use the two in cnjunction with each other as well as separately.
The powder has been around a while and in use in photo labs for sometime - especially the older ones or those that use glass negative carriers. I assume it is still available from a photographic supply house or someplace like Edmund Scientific or another scientific supply house. It is a very fine powder and should not effect the scan significantly as long as you use it sparingly. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Anthony Atkielski Sent: Thursday, September 26, 2002 7:52 PM To: [EMAIL PROTECTED] Subject: [filmscanners] Avoiding Newton rings I use the glass 120 film holder on my LS-8000ED because I need to be able to hold the film flat, however, I have a lot of trouble with Newton rings. The weird thing, though, is that some images have multiple instances of the rings, and others have none. This implies that the rings are not inevitable when scanning, only common ... so there must be a way to avoid them. What causes the rings on some images but not on others, and what can I do to avoid them when preparing and loading the film? ---------------------------------------------------------------------------- ------------ Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body ---------------------------------------------------------------------------------------- Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body
