Wiktionary (0.00 / 0 votes) Rate this definition: shutter speed (Noun). The duration of time for which the shutter of a camera remains open when exposing photographic film or other photosensitive material to light for the purpose of recording an image.
Many sports use very fast shutter speeds to capture the peak moment and freeze it in time. If the subject of your photo is not moving, or you want to show the passage of time (with a running river or waterfall), then you can use a slower shutter speed.hutter speed is measured in fractions of seconds and seconds. Here is an example of shutter speed numbers, from fast to slow: 1/2000 1/1500 1/1000 1/750 1/500 1/350 1/250 1/180 1/125 1/90 1/60 1/45 1/30. Realize that 1/2000 of a second is incredibly fast and is not a shutter speed that you will typically use.
