Christian MarclayCyanotypes

Christian Marclay’s photograms reinvigorate two nearly-forgotten media: the cassette tapes of the 1970s and ’80s and the cyanotypes of the 1840s. The cyanotype process dates to the dawn of photography and was developed by the English scientist Sir John Herschel. Utilizing a light-sensitive chemical mixture, cyanotypes are created by placing objects directly onto the surface of coated paper. The resulting blue photograms reveal a silhouetted image that varies in shade with the opacity of the objects.
