To take the pictures in my infrared photography album, I had to hack a camera to see the infrared spectrum. Digital cameras are inherently sensitive to near-infrared (just past red light on the spectrum) light, but manufacturers place an infrared-blocking filter right over the digital sensor to remove the effects of this sensitivity. I opened up a Canon A720IS camera and physically removed this filter, allowing the sensor to record both visible and infrared light. To complete the infrared camera, I had to put a filter that blocks visible light, but allows infrared light to pass on the camera. I used a piece of exposed, developed film over the lens to do this. This is a set of pictures documenting the removal of the small filter inside the camera.
