||The exercise is devoted to the question of how history studies can meet the methodological challenges as a result of the digitization of photographs and the emergence of digital photography. How do digital databases and the digitization of photographs from the 19th and 20th centuries change historical work? What consequences do the increasing visibility, circulation and multiplication of image documents have on historiography? How does digital photography differ from analogue techniques such as daguerreotype, Kodak clipper photography or Polaroid photography? What potential is there in tools like the screenshot for the historical method? And how do blogs change the writing practice of historians? The exercise is carried out in cooperation with the ETH Image Archive and the Historical Photography Collection of the State Museum Zurich. As proof of achievement, the participants write an essay based on their own research on digitized images and image stocks as a blog post for the ETH Image Archive or the State Museum (approx. 10,000 characters). The first version is to be submitted on May 21, 2021, revision by June 18, 2021. The exercise is a face-to-face event. References: Mirco Melone, Between Burst of Images and Treasure of Images.
