Everyone enjoys watching science fiction or fantasy films for their vast imagination. They take us into a world of their own and never fail to fascinate us every time we view them. They make us imagine how it would be like if we could live in a world like that. On the other hand, everybody does have a question how these films are shot and how a world like this could be created just for the sake of a movie.
The answer is, none of the fantasy stuff we see on movies is real. They are visual effects created on computers and added on the stage of post production to enhance the film. They are created on dedicated software applications to make them look appealing to the viewer. These effects are otherwise termed as VFX.
