the mans arm would also be blurring as it would still be moving while the ball is travelling... also would the ball really be so perfectly round?

Good point on the arm, but the ball would not change shape. Maybe you've never seen a real baseball, but they are "so perfectly round," and do not change shape as they travel through the air ~ They're quite hard little things...

I'd lose the ball image at the pitcher's end, but good idea.

Nice idea..good luck

can you refer me to a link to an actual shot of a baseball being thrown at highspeed with a trail... so that it can dis-prove my comment on that then?...

Very nice work author...Movement is well made...best of luck

I think the blur could benefit from a little curve. Right now it looks like their in space with no gravity. Good luck!
