Yes, that's true. All my IR pictures are made with an IR filter (Hoya R72 probably was the code name). Well, do you know how to make pictures with IR filter? (you can reply here)... Anyway, it's not hard at all making those pictures with an IR filter, at first I didn't get it how to make them step by step because many users were writing these "manuals" so abstract.... Let me know, but I definitely would recommend buying an IR filter. No doubt about that.
