I normally try to take a very low angle when photographing waterfowl. Because the light on this day was so flat, I decided to shoot from a slightly elevated angle. This would help to capture some of the shimmer on the water's surface. I thought this would help make the image a bit stronger by adding at least some contrast and depth to it. More action would have been welcomed, but he was content simply to float in loose circles. I am happy with the image nonetheless.
