Glory with airplane shadow

Glory with airplane shadow: The shadow of the airplane on a layer of clouds. The colorful glory around the shadow is cased by the diffraction of light in small water drops, similar to a rainbow. I've enhanced saturation and contrast a bit to make te colours more distinct. Nikon D200, 1/320 s, F/9.0, 52 mm, ISO 200, Sunday, January 4, 2009 15:10:59
