Regular #25 red filter won't give you the maximum IR effect. Ilford suggests a darker red, and even sells their own red gel filter. (Why isn't this info isn't in the box?) I've gotten a nice "black sky" effect by stacking red and polarizing filters. The Rollei red filter seems to do better than a #25, too. 1/125 @ 5.6 in sunlight. Phil Stiles NH USA
