That image was actually quite simple, it was taken with a Canon 5D Mark 2: 24MM 15 second exposure ISO3200 F2.8 As I recall it was a full moon or close to it but that is ok for such a short exposure, I had planned to do some star trail photos that night but the moon stopped me. I have several exposures of this image of different lengths of time but I liked this one the best. Here iby RoguePhotonic - Backpacking and Hiking Yosemite and the Sierra
