The following statement is only partially correct. Yes your exposures will be much faster, however a tripod will still be required. You will have to frame the shot, lock-down the camera and then apply an IR filter.  The Hoya IR 72 (which is the most popular) filter is practically opaque to your eye. Full conversion (with the IR filter on the sensor) is by far the best way to go. I use a fully converted 20D and have extensive experience with digital B&W IR. Look at www.pbase.com/garyallenbrown there are several hundred B&W IR images.

  With this option and an external filter, your exposures will still be pretty fast and you won't generally need a tripod. Super long exposures are usually due to having an IR blocking filter on you sensor AND an IR Pass filter on the lens, each blocking substantial portions of the visible and IR spectrum.

  And don't assume IR capability you will be able to record heat. The sensors in digital cameras only respond to the "near infrared" spectrum and are nowhere near the heat end of the spectrum. That requires a special camera and sensor.
