moonbow

This past week, friends of ours were down to visit and work, and we took the opportunity on Tuesday night to see the moonbow at Cumberland Falls. A moonbow is a rainbow caused at night by the light from the moon hitting the mist from the falls at just the right angle. This picture, although it looks like it's taken during the day, was actually taken at night. One of our friends graciously allowed me to use his tripod, so I set the aperture for f/4.5 and left the shutter open for 30 seconds. I was pretty excited with the result.
