This image caught my eye because of the minute detail shown by stopping the motion of this moment. You can see ball fuzz hanging in the air on the left, and detail in the arm muscles, both from Nadal's effort and from the movement of his swing. That level of detail can't be matched in typical TV footage of the match.
