Digicams vary in how well they block out infrared. If you have one that lets through a good deal of IR, you can just use a R72 filter over the lens and take IR shots in any conditions. See my digital IR folder at http://photo.net/photodb/folder?folder_id=817145.
This was an Olympus C-7070 digicam. I found out by chance that the Olympus range tend to be good IR performers. Don't know about Fuji.
My IR filter cost about £12 on eBay. (It helps that I have a filter screw thread on the camera.)
