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.
The rule of thumb When I started in photography the rule of thumb was really simple. When hand holding your camera the shutter speed should match or exceed the lens focal length. In other words if you wanted a sharp, shake free shot with a 50mm lens your shutter speed would be 1/50 th sec or faster. Whilst that was fine in its day the world has moved on and so has my rule.
