Colour Ultraviolet Nikon Coolpix 990 Images

These images are taken on a Nikon Coolpix 990 colour digital camera.  Two images are taken on the same scene, one unfiltered (RGB) and another through a UV-transmitting B+W 403 filter.  The green and blue channels of the unfiltered image are merged with the UV image, producing the false-color UV image.  The results are very similar to the images produced with the film and QuickCam techniques.
