'In photography, shutter speed is a common term used to discuss exposure time,
the effective length of time a camera's shutter is open. The total exposure is
proportional
to this exposure time, or duration of light reaching the film or image sensor.' *
i think when you use a slow shutter speed you can get photo's that look
magical, because by leaving the shutter open for longer it allows the
camera to take in more light and you end up with pictures that a filled
with what seems like the light moving and dancing around the photograph.
