The German artist Wolfgang Tillmans came of age in the 1980s, long before the existence of digital photo-sharing platforms, but he has always seen photography as an inherently social medium (and one that’s as sensitive and fragile as human relationships). In this interview with artist, writer and Index magazine publisher Peter Halley, excerpted entirely from the Phaidon Contemporary Art Series book Wolfgang Tillmans and re-published here on the occasion of his latest show at David Zwirner in New York, Tillmans reflects on his early career and his influences from Super-8 home movies to club culture.
