Joiner – Collage Camera is a camera app conceived as an artwork: by tracing a finger across the screen, users can “crop” fragments of the landscape and generate collage photographs in real time, with the immediacy of drawing. By shooting with slight shifts in angle and time, or by combining distant places within a single frame, the app lets users create and share collages with endlessly varied results. The work was made as an homage to David Hockney’s Joiners, a group of photo-collage works composed of Polaroids and other photographs. In 2012, the Tokyo Photographic Art Museum acquired the work together with an iPhone 3GS on which the app was installed; over time, however, battery deterioration made it difficult to power on. For this project, exonemo reexamined both the program and the original device and completed the migration.
