Fancy being an infrared detective? Hardware hackers are raising $30,000 on crowdf unding site Kickstarter to cut the cost of infrared cameras, which citizen environmentalists use to spot sewage spills in wetlands, for example. Red light is absorbed by plants during photosynthesis but infrared is not - so healthy plants should reflect a lot of infrared light. The idea behind the project is to buy cheap digital cameras and fit them with a "superblue" filter. This forces the red channel of the camera's image sensor to produce an infrared image. Infragram wants to sell the cameras for around $35.
