Lunar rainbow on Upper Yosemite Fall from Cook’s Meadow, May 2009



A full moon is coming up—Tuesday, May 17th, at 4:08 a.m. There should be plenty of spray in Yosemite Falls, so once again it should be possible to photograph a lunar rainbow, and I expect that many photographers will be in Yosemite trying to do just that. If you’re one of those people, last year I wrote some lunar rainbow photography tips that you might find helpful.
