There are very few places at which to photograph a Moonbow. Lower Yosemite Fall in April is one such place. One needs bright moonlight (nearly-full Moon), the Moon to rise above the south rim of Yosemite Valley, sufficient mist & spray, clear skies, dark skies (Sun> 9 degrees below the horizon), and geometry. On April 13, all of this came together. From 8:20 PM – 9:40 PM I worked to capture the Moonbow, keep the mist from my camera lens, and enjoy this phenomenon. It is so interesting that you cannot “see” the Moonbow until you look at the back of your camera. Once you know the Moonbow is there, though, your eye can “kinda” tell where it is.
