I'd been meaning to get an IR-pass filter for a while; Dan you inspired me - now I have one. My first few pictures are in <a href="http://www.truffulatree.com.au/greenbridge.php" rel="nofollow">this collection</a>. Graveyards are most appropriate places for IR photography, methinks!

It's actually a high pass filter, of course, and the "early cameras" involved - well, the ones that started the moral panic, anyway - had switchable IR filters, not none.

(If it is a problem.) Some early digital cameras didn't have such filters, and users figured out that if they used them with IR-filters at beaches and swimmingpools, the result was... intriguing. Seems that some synthetic fibers used in swimwear are transparent at those frequencies. Anyway, if you know what you're doing, it's possible to remove that IR-lowpass filter. <a href="http://vodkapundit.com/archives/008882.php" rel="nofollow">Steve Green</a> got a guy to do it for him.
