I wandered into The Camera Shop in Traverse City, saw a 1Ds classic on the shelf and found it was converted to infrared and available for rental. I've always been curious about infrared, so I rented it for the last day I was in town. Unable to get a sense of its capabilities with a computer to check images(no CF reader with me), I just took some photos hoping something would turn out. I highly recommend The Camera Shop, by the way. I didn't think well-stocked, independent-local camera stores staffed with knowledgeable professionals still existed.
Camera Nerdery: For if you don't know, an infrared camera is one that has had its anti-aliasing filter removed and had an infrared filter mounted in its stead. As far as I understand it, the camera only sees the longer light waves below the spectrum of visible light, creating some interesting effects. When you look at the photos on the back of the camera, they are monochromatic-red; that is, the world looks as it would from the vantage of an alien hunting Arnold Schwarzenegger.
