I had a dream last night, and I was thinking about doing portraits. I was photographing Groucho Marx, and I thought, how do I convey something about this guy that's not already there? (Being a dream, of course, we're all familiar with images of Groucho). So I said 'shoes'. 'Shoes make the man, or at least they say something about him'. And I had Groucho put his shoe on top of his head. It was a brown wingtip with a bit of a red cast to it, and it was polished, but it wasn't recently done. It was clearly a shoe that had given a few good years of service. And then I kind of woke up, and I thought, to myself, 'hey, that's not a bad idea'.
