well saurabh,those visual elements in movies and television such as fog, smoke, lightning, breaking furniture, snow, or the like, that are used to effect reality in the picture or videospace and that are either impossible or impractical to produce firsthand. Special effects also account for those visual elements that are produced electronically and that create an imaginative reality in motion pictures such as Star Wars or the Star Trek series.
Greater flexibility came with the development of the optical printer, which made it possible to combine separate pieces of film and replace part of an image, thus allowing for effects such as characters flying through the air. Special effects have also been created mechanically on the set through the use of devices such as wires, explosives, and puppets and by building miniature models to simulate epic scenes such as battles.
