Hi Armand,
I didn't say anything about a "great photo." I wrote about getting a message across in a photograph. Very few photographs with a clear, quickly understandable "message" are "great photos." It's the photos that make you work that are great photos. The problem with this photo isn't that it's not simple. It certainly is. But it's not clear. The title has nothing to do with it. It's a picture of a light shining against a wall. As you say, it brings up some "visceral connection" for you, and that's fine, but it obviously doesn't bring up any such connection for the other people who see it. To go back to the idea of a "great photo," a great photo brings up visceral connections for practically anyone who sees it. Gene Smith's "Walk to Paradise Garden" does that. A light against a wall doesn't.
