They probably wait until ball compression isn't a factor....it doesn't take long for the ball to recover.


I am still fascinated by how they get the clear still pictures of the ball. 1/1000s exposure still leaves a smear of 5cm for a ball off a driver...
It's not dependant on frame rate (ie exposure) but flash speed. Actively triggered flashes (not RC time constant) are easily two orders of magnitude faster than that.
