The spontaneous, unexpected or random event is a vital component in numerous works of Expressionism, Dada, Surrealism, Fluxus and conceptual photography. And the camera snapshot seems intrinsically implicated in the workings of chance. But why today does chance remain a key strategy in artists' investigations into the contemporary world? This anthology analyses the meaning of these strategic spaces of uncertainty, poised between intention and outcome, and provides a new critical context for chance procedures in art since 1900.
