A shutter allows light to pass outwards for a certain amount of time. The speed of a shutter is controlled by the ring that is outside of the camera. The shutter is on the inside of the camera, one of the shutters performs the opening of the shutter to expose an image. The second shutter performs the closing, by following across the sensor.
