What is stop motion ?????

Stop motion is an animation technique to make a physically manipulated object appear to move on its own. The object is moved in small increments between individually photographed frames, creating the illusion of movement when the series of frames is played as a continuous sequence. The first instance of the stop motion technique can be credited to Albert E. Smith and J.Stuart Blackton for The Humpty Dumpty Circus (1898), in which a toy circus of acrobats and animals comes to life. Now it is being used all the time in modern day.
