Last night here in Arches National Park, Utah, my photo tour group and I took pictures of Double Arch after dark. My original intention was to paint it with light using a powerful flash I'd brought along, and we did do a few shots that way. However, we had a half moon in the sky, and I realized that the light from the moon was enough to provide a very interesting natural light on the arch. So, this picture is there result of a 20 second exposure at f/2.8 and 1600 ISO, and I used daylight white balance. I wanted to limit the exposure time to no more than 20 seconds to prevent the stars from becoming oblong shapes due to the rotation of the earth.

Jim - Thanks, Ray. The reason I could get a lot of DOF with f/2.8 is because of the distance from the camera to the arch. More distance, more DOF.
Thanks James. I used a 17mm focal length.

Ray Chilton - That's a great shot! I am surprised that you could get so much depth of field in excellent focus with an f stop of 2.8.

james - Hi Jim, great shot! What focal length did you use? (So I can figure out how close you were)
