Well I got back from Africa last Wednesday, worked 18 hours on Thursday and then headed to Yosemite on Friday for the weekend. I'm having a blast but my body isn't too happy with me right now.
This is a night shot of a moonbow at Lower Yosemite Falls. A moonbow (also known as a lunar rainbow, lunar bow) is a rainbow produced by light reflected off the surface of the moon rather than from direct sunlight. Moonbows are relatively faint, due to the smaller amount of light reflected from the surface of the moon. They are always in the opposite part of the sky from the moon. It is difficult for the human eye to discern colors in a moonbow because the light is usually too faint to excite the cone color receptors in human eyes. As a result, they often appear to be white. However, the colors in a moonbow do appear in long exposure photographs.
The conditions are right this week in Yosemite for moonbows, however, after some pizza and beer on Saturday night, it was looking like I wasn't going to get to see one because the sky was so overcast. I got ready for bed and I took one last look out the window around 10pm when I noticed it was starting to clear. I grabbed my camera and started running up the mountain in the dark. The wind and spray from the falls was powerful and in my haste to get up the mountain I didn't grab anything to wipe off my lens. I knew I only had two shots to get the elusive rainbow (one with the UV filter on and one the filter off). After that my lens would be so wet the shots would not come out. I took my best guess at the exposure and pointed my camera right into the spray. This was my second (and last) shot of the night and after that I just stood in the misty spray and enjoyed natures show. If you look close you can see the very faint second rainbow above the colorful one. It was very cool!
I guess I should take a look at my photos from Africa now...
