Talking about his new book A Ray of Light for this week’s Talks With Roger, author-photographer (and BGHB winner) Walter Wick reminded me of something that I knew but had gratefully managed to forget: we see everything upside-down, and our brains correct the difference. When I think about that I have trouble walking. But with so much in our world upside-down already, I can see why so many, many of us are having trouble with our footing!
