Shutter speed is the duration of time light is hitting the digital sensor or film. In other words, relate it to how long it takes the camera to record the image.
A slower shutter speed is used to create the feathered blur of water.
When you press the shutter button and take a photos does it sound like a fast “click” or a slower “cl i i i i i i i i ck?” Shutter speed can be fast, slow or somewhere in between. For example, 1/2000 of a second is pretty fast, 10″ (seconds) slow, in comparison, and 1/250 of a second, more or less, in between.
A faster shutter speed will “freeze the action” and capture subjects in motion with no blur.
