Usually shutter of a camera opens only for a fraction of a second just to let enough light fall on the photographic film or an image sensor in case of a digital camera, thus ensuring proper reproduction of the color shades and details of real objects on the photographic image. However, photography is not only a technique of making pictures, but it is also an art of creating authentic fine art works with interesting visual effects. Overexposure is one of the tricks professional photographers use to make excitingly vivid pictures. By opening a shutter for longer and thus letting more light into the chamber, photographers can make really breath-taking photographs, which look especially impressive, if showing flowing water, or cars moving on the night highway.
