This was taken around 11PM under a full moon in Yosemite National Park. The moonlight and spray from the falls create what is called a moonbow. Only visible as a bow of silver to the human eye, the long exposure brings out the colors and creates a scene that appears like daytime.
Sunset hitting the edge of Horsetail Falls in Yosemite National Park, creating the firefall look. Shot from across the valley with a 70-200mm lens at 150mm.
