Greta Arn of the New York Buzz watches the ball as she prepares to return a volley in mixed doubles' competition against Delaware in Schenectady's Central Park in August. "Sometimes, it’s hard enough to capture the ball, the player and the racket in the same frame of the fast-paced world of professional tennis. I was lucky enough this time to get the ball right in front of Greta Arn, and marveled at her concentration as she watches the split-second movement of the ball as she prepares to hit it back across the net."
