key concept shutter speeds and action
What shutter speeds do you need for moving subjects?
There are two ways to shoot a moving subject: first, you can freeze them entirely using a high shutter speed. Alternatively, you can follow them in the viewfinder with a slower speed so that they remain sharp but the background is blurred.
The distance and speed of your subject are the crucial factors, so it’s impossible to be exact about the shutter speeds you need, so these are simply guidelines.
