A speculative history of the last century and a visual journey through some of its least likely pictures. In 1922 a small French avant-garde review published a photograph of a glass plate covered in dust. The photographer was Man Ray, the glass was Duchamp's. The title was first View taken from an aeroplane, then Dust Breeding. It is abstract and it is realist; it is a work of art and it is a document, and Campany follows what dust has done to photography ever since.
