I was on a Photography workshop from K&S in Yosemite for 3 days. It was Canon sponsored so I borrowed the 5D and lens. I was walking around Cooks meadow looking for a good shot of Half Dome since there were some nice clouds forming and good light. The group of photographers I came with were all getting closer to me, listening to the instructor, about to get in my way, so I quickly got down and took the shot. I didn't have time to get the tripod out so I used the built in level, used HDR, and took the shots quickly.
