Glory with airplane shadow
Fig. 13: 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; Δt=1/320 s; f=52 mm; f/9.0; ISO 200; 4 January 2009 15:10:59
