AShutter Speed and Aperture

Two of the chief factors in determining exposure are shutter speed and aperture. By slowing shutter speed while increasing aperture, or increasing shutter speed while reducing aperture, you can achieve different effects while keeping exposure constant. Fast shutter speeds and large apertures freeze moving objects and soften background details, while slow shutter speeds and small apertures blur moving objects and bring out background details.
