The shutter in photography is a device that allows light to pass for a determined period of time to expose film or sensors and capture an image. It has parts and controls the depth of field, which is the distance between the nearest and farthest objects that appear acceptably sharp in the image. The depth of field can be large to have the entire image sharp or smaller to focus on certain objects.
