Shutter speed can be used to control light in an image. It can also be used
to free motion. Here are some examples of shutter speed used to control
how an image is displayed
This was shot with my Sigma
Macro 28-80. 1/32 at F32. You can see how the water show fluid motion in the
shot.
Here is the same picture set at
1/1000 at F7.1. Notice how the water droplets are frozen in the
picture.
