I was panning on the deer as they ran through the heron rockery in the CVNP and one of the herons was scared and was going the opposite direction. The panning was good for only the deer.
Here a Great Blue Heron in flight.
Here is an American Eagle flying over the lake.
Here is a Osprey flying with a fish.
Here is a sea gull flying over the water.
Here is an example of what happens when you don't pan. The standing gulls are in focus while the flying one was not. It could have been had I panned it but I just held still and shot..See what the others show on my side bar.
