What is the
function of the camera shutter?
In any camera,
the shutter is like a blind that opens and closes to let the light through.
So the purpose of the shutter is to control the length of time the light
reaches the CCD or film. While most cameras have shutter controls that
are measured in fractions of seconds, to a few seconds, exposures
can be made in minutes and even hours or at the other end of the scale
thousandths of a second.
the sensitive material receives becomes a combination of the shutter speed
and the aperture setting which controls the
amount of light falling on the film or CCD.
Faster shutter speed
Slower shutter speed
