Infrared Photograph

Ever since discovering BeyondSight, I've been rolling the idea of infrared around in my mind like a smooth pebble. Infortunately, when I asked the good folks at Henrys about an IR filter for a specific Canon L series Lens, they were confused "Are you sure you don't mean a UV filter?  Granted, the fellow was young, and likely not many folks ask for something as obscure, so I left it, to return to the 'net to see what else I could dig up on Infrared photography.

Taking IR pictures is harder than one might imagine.  Apparently it doesn't work so very well with digital SLR cameras - better with digital non-SLRs... so I've already got that going agains me. Something to do with the blocking of IR light in an SLR, and the fact that you can't see the composition in the LCD screen (really, i'm not convinced of the reasons why SLRs don't allow for that feature.) 

Using software to try and mae an IR feeling photo from a regular photo is hard too...Of course, in theor Adobe can do it, but only on a Sunday, and only when the wind is blowing from the east.

Suggestions anyone?
