Dziga Vertov • Senses of Cinema

Our eyes see very little and very badly – so people dreamed up the microscope to let them see invisible phenomena; they invented the telescope…now they have perfected the cinecamera to penetrate more deeply into he visible world, to explore and record visual phenomena so that what is happening now, which will have to be taken account of in the future, is not forgotten.

—Provisional Instructions to Kino-Eye Groups, Dziga Vertov, 1926
