This is a fun photo I captured on the trail in Boulder, Colorado. This is a moth that looks like a hummingbird. I stopped the action with a 1/2,500 second exposure at f/4, and increased the ISO to 4,000. Taken with the Canon 5D Mark III with a 70-200 mm lens. (This is a cropped version of the original image.)
