Named after the cloud pictures taken by American photographer Alfred Stieglitz in the early 20th century, “Songs of the Sky” opens at C/O Berlin to examine photography in the age of cloud computing. Featured artists like Evan Roth, Fragmentin, Trevor Paglen, Shinseungback Kimyonghun, Mario Santamaría, and Noa Jansma (image: Buycloud, 2020) explore nascent network technologies to invite questions about their effects on climate change, geopolitics, and how we see the world.
