The Kuleshov Effect

Kuleshov edited together a short film in which a shot of the expressionless face of Tsarist matinee idol Ivan Mozzhukhin was alternated with various other shots (a plate of soup, a girl, a little girl's coffin). The film was shown to an audience who believed that the expression on Mozzhukhin's face was different each time he appeared, depending on whether he was "looking at" the plate of soup, the girl, or the coffin, showing an expression of hunger, desire or grief respectively. Actually the footage of Mozzhukhin was the same shot repeated over and over again. Vsevolod Pudovkin (who later claimed to have been the co-creator of the experiment) described in 1929 how the audience "raved about the acting.... the heavy pensiveness of his mood over the forgotten soup, were touched and moved by the deep sorrow with which he looked on the dead child, and noted the lust with which he observed the woman. But we knew that in all three cases the face was exactly the same."
Kuleshov used the experiment to indicate the usefulness and effectiveness of film editing. The implication is that viewers brought their own emotional reactions to this sequence of images, and then moreover attributed those reactions to the actor, investing his impassive face with their own feelings.

Filmmaking Techniques

A great beginning tutorial for editing and type of shots.

Montage Theory - Sergei Eisenstein

Metric - where the editing follows a specific number of frames (based purely on the physical nature of time), cutting to the next shot no matter what is happening within the image. This montage is used to elicit the most basal and emotional of reactions in the audience.

Rhythmic - includes cutting based on time, but using the visual composition of the shots -- along with a change in the speed of the metric cuts -- to induce more complex meanings than what is possible with metric montage. Once sound was introduced, rhythmic montage also included audial elements (music, dialogue, sounds).

Tonal - a tonal montage uses the emotional meaning of the shots -- not just manipulating the temporal length of the cuts or its rhythmical characteristics -- to elicit a reaction from the audience even more complex than from the metric or rhythmic montage. For example, a sleeping baby would emote calmness and relaxation.

Overtonal/Associational - the overtonal montage is the cumulation of metric, rhythmic, and tonal montage to synthesize its effect on the audience for an even more abstract and complicated effect.

Intellectual - uses shots which, combined, elicit an intellectual meaning.
