[MM] has built a simple lighting adapter for analyzing skin lesions. Different layers of the skin absorb different parts of the light spectrum. By shining those particular wave lengths on the skin you can get an image of the lesion in various layers. This camera adapter is designed for a Nikon Coolpix E3100 digital camera. The ring of LEDs contains blue, green, red, and IR. White is included as well for taking normal pictures. A polarized filter is used to cut down on light reflections from the skin surface. The device does have some calibration issues since it was soldered by hand, but the preliminary results look very promising.
