Somewhere … Over the Rainbow


This wonderful rainbow lasted only a few minutes, as most do, shining in the brief interval when sunlight and raindrops are at their combined best.

I captured this rainbow off the back deck, on June 2, as a storm receded to the east and the Sun broke through in the west, ideal circumstances for catching a rainbow, at least photographically.

This was a classic bow, showing the inner main bow and the fainter outer secondary bow with colours reversed. The sky is bright inside the the inner bow from scattered light from the raindrops, and darker between the two bows where there is an absence of scattered light, a phenomenon called Alexander’s Dark Band after the ancient Greek astronomer who first described it.

I used a Canon 60Da and 10-22mm lens for this, at 10mm for wide-angle coverage of almost the entire rainbow.
