We were photographing the old mormon barns in the Tetons, and hoping to get a good sunrise image. However, some clouds were rolling in and it wasn't looking good for a morning photo. However, the sun peeked out for a very brief moment hitting the barn. I was lucky to have the barn in my camera frame when this happened. I was also lucky to have the exposure set because I had metered off another area that the sun had hit a few moments before. - Kevin
