“Moonbows” are rainbows that appear at night under moonlight, and are difficult to see with human eyes but beautiful when captured in long exposure photographs. There aren’t many places on Earth where this phenomenon can be regularly witnessed, but a few of them are found at the waterfalls in Yosemite.
Steven Bumgardner, the video producer for the national park, spent two years moonbow hunting and shot over 20,000 still photos with a Canon 5D Mark II to create the time-lapse sequences seen in the video above. After watching, you might want to add “moonbows” your list of things to see and photograph (along with the northern lights, perhaps).
Thanks for sending in the link, Steven!
