Dziga Vertov's groundbreaking and experimental silent documentary film "Man with a Movie Camera" is famous due to the vast range of photographic techniques that the film maker used. The 1929 film presents life in several Soviet cities, capturing citizens at work and at play. Vertov's film has no storyline or actors, but it is acclaimed for its influential experimentation. In the short film, he employs "double exposure, fast and slow motion, freeze frames, jump cuts, split screens, extreme close-ups, footage reversed, and stop motion animations." He emphasizes that film has no boundaries.
The above movie still is taken from the film's opening shot and provides an example of Vertov's experimentation. In the image, he superimposes a shot of the cameraman setting his camera up on top of another camera.
