Shutter speed is measured in seconds. A typical shutter speed for [[photograph|photographs]] taken in sunlight is 1/125th of a second. Very short shutter speeds are used to freeze fast-moving subjects such as sporting events. Very long shutter speeds are used in low-light conditions such as night or to intentionally blur a moving subject for artistic effect. |

In [[cinematography]], shutter speed is a function of the [[frame rate]] and [[shutter angle]]. Most motion picture film cameras use a rotating shutter with a shutter angle of 170° to 180°, which leaves the film exposed for about 1/48 or 1/50 second at standard 24fps speed. |

In photography the time which the shutter is held open during the taking of a photograph to allow light to reach the film.
In combination with variation of the lens aperture, this will regulate how exposed the film will be. A fast shutter speed will demand a larger aperture to avoid under-exposure, just as a slow shutter speed will be offset buy a very small aperture to avoid over-exposure.
Shutter speed is measured in seconds. A typical shutter speed for photographs taken in sunlight is 1/125th of a second. Very short shutter speeds are used to freeze fast-moving subjects such as sporting events. Very long shutter speeds are used in low-light conditions such as night or to intentionally blur a moving subject for artistic effect.
