Shutter speeds can be controlled through the Shutter Priority mode: you choose the shutter speed via the command dial, and then the camera automatically selects the aperture. Or you can set it in Manual mode. The selected shutter speed generally appears in the data-panel readout display.
As the shutter speed increases, the amount of light reaching the sensor decreases. For example, a shutter speed of 1/125 of a second lets in twice the amount of light as a shutter speed of 1/250 of a second and half the amount of a shutter speed of 1/60 of a second. Slow shutter speeds will allow moving objects to blur, while high shutter speeds can be used to freeze motion.
Box 3.4 Shutter Speed Rule
Using a shutter speed equal to or greater than the focal length of the lens will help to ensure sharp, shake-free exposures.
To avoid blurry images caused by camera shake, follow the shutter speed rule: Use a shutter speed equal to or greater than the focal length of the lens. For example, when photographing with a 125mm focal length, use a shutter speed of 1/125 of a second or higher.
