The biggest revolution in the history of special effects was the evolution of stop motion, followed by miniatures, and Matte Effects. Now, the extent of usage of special effects has grown to such an extent that most of the modern movies are built around just special effects.
Stop motion, commonly referred to as stop action, and frame-by-frame, makes it possible to make a physically manipulated object appear as though it was moving on its own.
Basically, the original object is moved in small increments with the help of a number of photographed frames, creating the illusion of actual movement when the sequence is played at a fairly high speed.
This superb technique has allowed the animation experts to create amazing stop motion effects that look highly real, and give a magical impact.
For instance, take a look at this photo, which looks as though the coin is really moving!
