A collection of found photographs that the artificial-intelligence software Clarifai categorised as "schmutzig" ("dirty"). The photographs, found in one particular image library, date from the late nineteenth century, the time of rapid scientific discovery, mass production and industrialisation, and depict nature in its pure form alongside human interventions in the landscape. Wysocka is as interested in the medium of photography itself as in its subject: dirt, dust, blur, scratches and cracks on the negatives leave an imprint of the passing of time and give the experience of browsing the book an uncanny nostalgia. Faded and bleached colours are reproduced and enhanced by combining two printing techniques, offset and Risograph.
