First off, you're going to need a filter, probably a Hoya R72 which is mostly used, but there are others with stronger visual spectrum blocking abilities that you can get, although they will require very long shutter speeds. Different cameras, with different sensors have different sensitivities to the infrared spectrum and I'm not sure how sensitive to the infrad spectrum your Canon is, but I have a feeling it's not terribly sensitive, which again, means very long shutter speeds (which means more noise too). A tripod is a must! You will most likely need to focus your scene without the IR filter on as AF most likely will hunt and not find something to focus on. Resulting images can be quite soft, so use the sharpest lens you have.
More and more photographers are having their DSLRs modified so that the hot filter over their sensors are removed and an IR filter put over the sensor. Others opt for P&S cams which can have far greater sensitivity to the IR spectrum, and can even be handheld during exposure. Cameras such as the Nikon Coolpix 995 is an example. |
