Rodchenko was one of the most versatile constructivist and productivist artists to emerge after the Russian Revolution. He worked as a painter and graphic designer before turning to photomontage and photography. His photography was socially engaged, formally innovative, and opposed to a painterly aesthetic. Concerned with the need for analytical-documentary photo series, he often shot his subjects from odd angles—usually high above or down below—to shock the viewer and to postpone recognition. He wrote: "One has to take several different shots of a subject, from different points of view and in different situations, as if one examined it in the round rather than looked through the same key-hole again and again."
