Things move a lot in a millisecond, although it's certainly easier to see that in small-scale images rather than this lighthouse one. https://sib.smugmug.com/S

This is a picture that I took in 2009; you can see the ball coming off Ken Griffey's bat after breaking it.
A major league fastball comes off the bat at 100+ miles per hour (45 m / s). The shutter speed was 1/640s (about 1.5 msec). The ball is about 7.26 cm in diameter.
- ComputerGuru 9y agoNice example. To make your point clearer: that motion blur is how much the ball moved in just 1.5ms
- sib 9y agoExactly, thanks for clarifying. And also why I was shooting with single shots to try to time the ball close to the bat. Given a camera that took about 5 frames per second (200msec between frames), the ball would move about 29 feet (8.8m) in between frames. The breaking bat was a nice surprise.
