Kuleshov effect
The Kuleshov Effect was first used in Russian films. Directors Sergei Eisenstein, Vsevolod Pudovkin and Dziga Vertov used the effect. Russian films include The Battleship Potemkin, October, Mother, The End of St. Petersburg, and The Man with a Movie Camera.  American and other European directors have also used the effect. It is now a common element in movies. It is important for editing movies. It is also useful to understand the context of an image. An image will often follow another image in time. Images can also be right next to each other at the same time.
