The shutter is a mechanical device that controls the length of time that light is allowed to act on the film. Most standard cameras allow us to use a range between 16 second and 1/1000 second. You might be wondering, why anyone would use a long shutter time of 16 seconds: I've used this and even longer shutter times when taken lowlight landscape images. I would always advise the use of a tripod with these long exposures time to avoid blur images.
