So (which seems to be the way everyone interviewed on television begins an answer these days), when I was in Bologna at the beginning of this month, I was thinking about what kind of image I could submit for this year's Summer Exhibition at the Royal Academy, and remembered a book I'd read last summer with the title Why It Does Not Have To Be In Focus while I looked down on this crossing.  I took a few shots and decided that this one might catch the eye of the judges, so (as in therefore) I sent it in today.  Luckily I didn't have to provide a statement about the lack of focus dematerialising the scene and dislocating the people in it from the fabric of reality.  I just can't do art-speak.
