Thanks again everyone,
cosmonaut I shoot digital and use a Hoya R72 IR pass filter on my 300D to get the effect.
Im sorry but I can't offer you any advice on IR film having never used it. I do know that some people on the forum have experience with IR film and would more then likely be happy to share their knowledge. Try asking in the Alternative Techniques board in the film section, Im sure you will get lots of help. Good luck, IR is a lot of fun.
