Been messing around IR photography the past couple of weeks. This is what's happened!

First, I'll be talking about two different kinds of IR filters. An IR transmitting filter (a filter that only lets IR light through), and an IR Filter (a filter that blocks IR light).
You'll need a camera and a IR transmitting filter. Most digital cameras don't work very well for IR because they have an IR filter in front of the sensor to filter out any IR light. The reasoning behind this is because camera sensors are just as sensitive to IR light as they are to visible light, and without that filter the IR light would interfere with automatic metering and focusing of the camera. To get best results with IR photography you would need to remove this filter.
I shoot my IR with a Panasonic DMC-FZ30 and a Hoya R72 IR transmitting filter. My Panasonic still has that IR filter before the sensor so I need to set my shutter speed really slow to get a good exposure in daylight. I am essentially blocking out all visible light before the light enters the lens with my IR transmitting filter, and then the IR filter just before the sensor blocks most of the remaining IR light. A tripod, no wind, and a very bright and sunny day are all necessary to take a good IR shot with my unmodified FZ30. If I were brave I could crack open my camera and remove that IR filter, I would then be able to take IR shots hand-held like a regular picture. However, that would render the camera not very usable for regular non-IR shooting without a regular IR filter on the lens.
Hope that helps!

Might be something to try in a few years when I step up to the more professional version of my camera (now I just have the Canon 450D) [IE once I have this as a backup camera that I could risk ruining.]
Any idea if my camera would work on a tripod with just the R72? [I would prefer it if I could do it handheld as the main idea was to use it for animal photography at night using some sort of IR flash if possible, but I think it could be interesting to try it this way for now.]

They're talking about exposures of 30 seconds at f4 and 100ISO. So the IR filter is quite good at blocking IR light to the sensor. But you can turn up the ISO and, if your lens permits, widen the aperture to get faster shutter speeds.
