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.
However, there is a limit. You cannot use this rule for very slow shutter speeds unless you use a tripod. For example, if you are photographing a landscape scene at 20mm then I can promise that setting your shutter speed to 1/20 of a second will not advance your clarity.
