Oh, and one more thing... the final product depends on what color the image appears in the camera. The colors depend on the sensetivity of the camera to IR, and every camera is different.  My Canon and my Nikon both produce a deep purple image (less sensitve), while my Fuji creates images with much more tonal and color range, between light pink and deep blue, making it much more useful for IR. Just thought you might like to know! =)

P.S. If you want to see before and after shots from each of my cameras, I can do that =)
