hi All (again)
the tips I post usually works for me, but thats not to say they wont work for you, one other thing which I have found is a remote switch, which will save your tons of time.
the reason I use a red filter is too cut out a lot more of the IR spectrum, to give me a compressed tones image, which I then usually post edit in PS CS2.
Now when you take an IR picture, what you are actually seeing is the reflected IR light from the object you are taking. So two other points.
The foucs point will change, so watch out and NEVER AUTO FOCUS, alwys focus first then, place the filter in.
higher ISO's will alwys lead to more noise (grain for film fans). I have tried this will HIE IR FILM (kodak) and anything over 6 seconds will lead to reciprocity failure.
if anyone has a IR capable camera to donate, dont forget me
