'''Shutter speed''' is the amount of time a cameras shutter is held open. The normal reason for adjusting shutter speed is to compensate for various levels of [[light]]. Generally it is preferable to have a higher shutter speed, but in lower levels of light, it is not always possible.

Common shutter speeds are 1/500, 1/250, 1/125, and 1/60 of a second. If the shutter is held open for longer than 1/60 of a second, it can be difficult to avoid blurring.<ref>http://digital-photography-school.com/how-to-choose-the-right-shutter-speed</ref> With a great enough aperture (shutter opening), shutter speed can be increased to 1/2000 second or greater to significantly reduce blurring. This high-speed method is ideal for photographing or recording objects in motion.
