Have you ever taken a photograph of a person wearing a pair of sunglasses in infrared and noticed that they are totally clear? This is the effect that I am talking about. The general rule is that the cheaper filters suffer much greater loss in infrared and the variable ND filters do not work well at all (yes, even the expensive Singh Ray).
