It is the mundane details that the Stasi recorded that surprised me, from how many tins of fish he brought to the number plates of cars going in and out of a drive. There was also a clumsy nature to the observations, losing their trail and being unsure of numbers. They also referred to him as the cyclist, yet he didn't actually own a bike! Hauswald sent many photos to the west for publication, and this led the Stasi to attempt to art critique his work, all of which is contained in his security files.
I was lucky enough to go to a showing of this film at the CCA, where Harald Hauswald and Marc Thummler were present to discuss the work. Hauswald spoke of his experiences - being followed by ten Stasi agents, being questioned and even arrested, all for taking photographs. The film is a good starting point to debate what is freedom of expression, and do we take these rights for granted?
