A player landed after a high serve and the camera caught the follow-through frame where both feet left the ground, both arms swung forward, and her entire body hung in the air like a person who had been launched from a catapult and was still deciding where to land. The expression combined the satisfaction of a clean serve with the surprise of temporary flight.
Serve follow-throughs involve the entire body crashing forward. The toss arm comes down. The racket arm swings through. The legs drive upward and then land. During the airborne frame, the player's face displays a micro-expression that does not exist at any other moment in tennis — the look of someone who has committed fully to a motion and is now a passenger until gravity finishes its part of the job. This photo froze that passenger moment, where the serve was done and the landing was pending.
