Action painting
The emergence of Abstract expressionism in the 1950s with Jackson Pollock and Willem de Kooning gave way to Action painting, a technique that emphasized the dynamic movements of artists as they splattered paint and other media on canvas or glass. For these artists, the motion of putting paint on canvas was just as valuable as the finished painting, and so it was common for artists to document their work in film; such as the short film Jackson Pollock 51(1951), featuring Pollock dripping paint onto a massive canvas on his studio floor. Situationists in France, led by Guy Debord, married avant-garde art with revolutionary politics to incite everyday acts of anarchy. The "Naked City Map" (1957) fragments the 19 sections of Paris, featuring the technique of Détournement and abstraction of the traditional environment, deconstructing the geometry and order of a typical city map.
