After hearing Thomas Struth speak for two hours (and show a whole range of slides illustrating his career, going backwards from the most recent to black and white cityscapes from the 70s, including a photo of New York in 1978 that I particularly liked - it summed up the more than slightly sinister shabbiness around Spring Street when I first visited) - it was kind of hard taking a photograph. I was very struck by his opening statement that "to make a photograph, you have to have a reason." I don't suppose he meant taking a photograph as one's personal daily assignment. So what is the reason behind this? I think that's a question that I should ask myself more often.
