“I collect a lot of stuff, and sometimes I like to see it as raw material I could use to tell another story and do something new,” says Thomas Sauvin. Hand-colored, his project with Chinese animator Lei Lei, is a good case in point. A collection of 1168 images which have been scanned, reprinted and repainted in bright, deliberately artificial colours, it’s the opposite of the usual archive work. But it’s part of the Beijing Silvermine Archive, he says, a collection of negatives Sauvin first started up by salvaging strips from a recycling plant in the Chinese city.
