There was a great photo in the Washington Post, of a rookie pitcher who pitched Tuesday evening. He's been hyped since he was drafted, and really lived up to it in his major league debut.
The photo is here, with an explanation of technique, which has one mistake, I think. The photographer must have meant, "rotating the zoom ring," not, "rotating the lens." If registration is required to view the page, it's free.
My first thought was that it must have been composited, but then I realized that the pitcher's lateral motion at this point exactly matches the apparent motion created by the zoom in the crowd heads behind him. Incredible concept and execution.
