I spent the last two days in the Whitechapel Gallery at a symposium called On Perfection, a subject close to my heart. Lots of thought-provoking lectures and presentations from artists, academics and photographers, and most of it made perfect (sorry) sense. But what I found somewhat disconcerting was the deference shown to the Are, Bure, Boke (rough, blurred and out of focus) images of certain Japanese photographers. Perhaps I'm trying too hard. After all, nobody's perfect.
