Digital camera hacked into near-infrared camera
The Public Laboratory for Open Technology and Science(PLOTS) provides this detailed tutorial on hacking a Canon Powershot A490 digital camera to allow it to record images in the infrared light spectrum. The mod involves opening the camera and removing the infrared light filter. To view only infrared light, replacing it with a piece of exposed color photographic film taped over the front of the lens which filters most visible light but allows infrared in.
Such a modded camera is useful for studying the amount of infrared light reflected by plants, which is thought to be an indicator of their health.hacks, infrared and tagged Canon A490, digital camera, infrared camera.
