Heinrich Kühn :: Portrait of the Artist’s Son, Walter, ca. 1905 / source

Heinrich Kühn was one of the most influential amateur photographers in Vienna. Careful attention is paid to the repetition of circular shapes – Walter’s glasses, hat, coat buttons – that punctuate the broader expanses of dark or light earth-toned patches of colour. The tone in the photograph is the result of a complex printing process in which pigment was adhered to the surface of the paper through exposure to light.
