Oh no, you don't need a special camera. You just need to get an
infrared filter and put it in front of your lens. Of course you won't be able to see through your viewfinder, so I suggest setting it on a tripod. The exposures will be pretty long because there's a piece of glass in front of the sensor that actually filters out infrared (so only very little can come in). I modified my camera to get around this, and to make my camera more sensitive to IR. You should give it a shot, it's makes
boring pics look awesome.
