Talk:Anti-halation backing

Efke IR820 Aura also lacks an Anti-Halation backing and has a similar glowing effect to HIE. Though not the same. —Preceding unsigned comment added by 71.104.6.204 (talk) 05:36, 1 September 2009 (UTC)

rem-jet
The rem-jet backing for movie films is needed, besides antihalation, to allow for daylight loading of movie cameras. Kodachrome was commonly used in double-8mm (before Super-8) cameras, which also daylight load open reels of film. Most 35mm films, I believe the IR films being an exception, have a gray base to reduce light piping when loading, but also for antihalation. Most (paper backed) roll films don't have a gray base.
