EXAMPLE:
Shutter speed is the speed that the shutter remains open for when taking an image. A fast shutter speed is anything over 300/1 of a second, and causes a freezing movement as you can see in the water droplets in the image above. The shutter opens and closes so quickly it makes water look like ice, like it is frozen in time. Fast shutter speed is always good to capture movement, for example if a person jumps, you can capture them in the air and ‘freeze’ them.
