How do art conservators save video art from obsolescence? If a painting on canvas rips or a marble sculpture shatters to pieces, art conservators are trained to respond accordingly and repair it. Artworks that unfold over time – like videos and software based works – are a different thing altogether. These artworks are made using cutting-edge technologies that are constantly being updated. If the “canvas” or medium an artwork is made on keeps shifting, how do art conservators protect these works from obsolescence?
