Sun dog, retinex enhancement done with Graphic Image Manipulation Program There was a blue-purple band visible to the human eye when the sun dog is viewed through a polarized lens. The band is not strongly picked up by the digital CMOS sensor in the camera. The sun dog is a spectrum generated by prismatic ice crystals in a vertical alignment.
