Shutter speed: fast freezes--- slow shows

Shutter speed is all about capturing motion. To show movement you use a slow shutter speed which will capture the motion and blur it. If your subject is moving and you want to freeze the motion you use a fast shutter speed. The faster something moves the faster your shutter speed must be to freeze it. I think this phrase is very catchy and useful because it is so straight forward and tells you how to show motion in different situations.
