Author Topic: Loop Flash? Jeffry L. Johnson Jedi Master Film Handler Posts: 809 From: Cleveland, Ohio, USA Registered: Apr 2000 posted 08-09-2002 08:52 AM                        Maybe this was the source of "rubber screen"? Film Notes for the Reel People Troubleshooting and Prevention of Damage Kodak Publication No. H-50-4 Image Sharpness The Heat/Light Conspiracy "Screen image focus problems can arise when the heat becomes too great, especially if the humidity is high. New prints are more often involved than seasoned prints. If all of these adverse conditions are present, the screen image will appear soft and no focus trim will help. This is called flutter. As conditions become worse, the image will begin to go in and out of focus erratically making the screen appear to be made of rubber."  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 08-09-2002 09:39 AM                        Jeffry: Thanks. I was a mere youngster at Kodak when that one was written by Paul Preo in 1977. As I suspected, it was another term for "focus flutter". ------------------ John P.
