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.
1 Camera shake is when your camera is moving while the shutter is open and results in blur in your photos. 2  If youâre using a slow shutter speed (anything slower than 1/60) you will need to either use a tripod or some some type of image stabilization (more and more cameras are coming with this built in). Shutter speed is measured in seconds â or in most cases fractions of seconds. 2  The bigger the denominator the faster the speed (ie 1/1000 is much faster than 1/30). 3  In most cases youâll probably be using shutter speeds of 1/60th of a second or faster.
