Getting around to working on more of my images from Blackwater National Wildlife Refuge. Here are some of the Tundra Swans we saw at the refuge. Most of the time they were far out in pools along the Wildlife Drive. But occasionally we saw some fly by giving us an opportunity for some flight shots. These were on an overcast grayish blue sky day. The higher up the Swans were flying seemed to be a little bluer sky. Because of the gray day I had to raise my ISO higher than I usually use to get a shutter speed fast enough to stop the wing movement.
