Bright rainbow created by Sun low in west just about to set with raindrops in the air to the east, and light rain falling at the time. Taken with Canon 7D and 10-22mm lens at 10mm, in two sections, stitched together in Photoshop. Note: bright interior region inside inner bow, darker exterior region, supernumerary arcs along inside edge of inner bow at top, reversal of colours in two bows, and bright red portion of the spectrum from very red sunlight from low sun angle. Taken from southern Alberta, Canada.
