High School students watch a volleyball home game from the gym mezanine.

A home team player successfully dives to defend the opponent team’s spike and now needs to focus on a landing…soon. Volleyball is a fast game.
Technical: a high ISO due to low gym light (2000) and a fast shutter speed 1/640 to stop motion of the player, but not the ball, a shallow aperture of f/2.2 to isolate the main subject and blur the background, and a 135 mm f/2.0 lens
