Shutter Speed: The speed at which a digital camera's shutter exposes the image sensor to light. A shutter speed of 1/60 means that the sensor is exposed to light for 1/60th of a second. Faster shutter speeds are good for 'freezing' fast-moving action; slow ones allow you to intentionally blur the movement of your subject to emphasize motion, such as water traveling over a set of falls (these types of shots may require a tripod, since the human hand cannot hold a camera steady for very long). Simple digital cameras may have very little shutter speed adjustment; more sophisticated cams often have between 9 and 15 shutter speeds. Many cameras also offer shutter speed priority mode.
