Kuleshov effect
Kuleshov apparently did experiments in the 1910s. It is not clear if these experiments took place and if the results were real. Kuleshov would show an audience one image. He would show the image again with a second image. Kuleshov changed the second image. Each time there was a different second image, the audience had different emotions. The audience thought that the actor changed his facial expression with different images. Kuleshov said that the two images together changed the emotions. The context of the image was important. The second image created the context.
