Here's a 100% crop of a great horned owl photo taken 9 minutes before sunrise this morning. I got better shots of the owl, but this was the first shot and it was a mere silhouette to my eyes. The bird took off right after this shot to a nearby tree and I didn't think I had even focused on the bird until I got home and downloaded my photos. I couldn't believe it!
