Shutter

The Shutter of the camera controls the time duration of the exposure of each frame being captured. There are shutters that physically open and close as well as many that rotate. There are also electronic shutters that switch the image sensor on and off to create the digital equivalent of a mechanical shutter. The shutter combines with the aperture to create the brightness or exposure. The shutter also effectively dictates the amount of Motion Blur that is seen in the resulting image.
