A image from my Sports Photography class assignment #2. Panning.

In this assignment we have to use a slow shutter speed relative to the speed of the subject and use a panning technique to blur the background and try to keep the subject in the sharpest focus possible.

This is from the mens indoor/outdoor track practice at the University of Tennessee at Stokley Athletic center.

I know I broke some traditional rules of composition by not allowing my subject to have "room" to move thru the frame. But I put him on the edge of the frame to help represent his speed in a subtle way. Get it?
