History editing

Kuleshov
Kuleshov edited together a short film in which a shot the expressionless face.Ivan Mosjoukine was an alternsted with various other shots e.g. a plate of soup,a girl in a coffin and a woman on a divan. This made the audience believe  that the expression on Mosjoukine's face was different each time he appeared, depending on whether he was looking at the plate of soup, the girl in a coffin, or the woman on the divan. Showing the face expressions of hunger, grief or desire, respectively. Kuleshov used the experiment to indicate the usefulness and effectiveness of film editing.

Eisenstein

• Metric
• Rhythmic
• Tonal
• Overtonal
• intellectual

When Eisenstein is doing a film. He mostly concentrates on the structural issues such as camera angles, crowd movements and the montage. What Eisenstein did was to force himself to do issues for the public articles of self-criticism and commitments to reform his cinematic visions to conform the increasingly specific doctrines of socialist.

Soviet montage
The Kuleshov effect is a film editing effect also known as a montage. This demonstrates Soviet filmmaker Lev Kuleshov in the 1910's and the 1920's. It is a mental phenomenon by which viewers derive more meaning from the inteaction of two sequential shots than from a single shot in isolation.
