Anytime Tom :-) you just got every bit of knowledge I have on IR filters and shooting.... lol
I am very much a point and click and hope it works kind of guy. I am so new with this thing :-)
Kort on here seems to know a lot about IR... and he seems like a really great guy I have been reading a lot of his threads.... He might be able to answer anything you want to know about it... or point you in the right direction....

I got into it after seeing the works of....... http://www.myinfrared.com/
and talking to a guy that post images there.... His english was really broken... but after a few long talks I finally bought a camera and sent it off....
Have a great Day Tom!!
