Rainbow High-Contrast

The most spectacular rainbow I've ever seen, several minutes after it really reached its peak intensity. Rainbows don't photograph particularly well, but with the contrast turned up a bit, you can clearly see the supernumerary arcs. They're due to interference between waves of light of slightly different path lengths passing through the water droplets. The secondary rainbow was also visible for several minutes, but had disappeared by the time I'd gotten to a place to park.
