So, what do we have here? This picture is a bit narrow in appeal. If you're an aficionado of certain kind of street photography you're going to see some things in here. If you're not, you probably are not. The "culture" to which this picture might appeal is kind of narrow. When I "explain" it, I'm not correcting your understanding of the picture. Your understanding is what it is. What I can do is explain a little bit of what's going on within that "culture" that does notice the relevant features of this picture.
If I'd shown a picture of a cross to a 12th century Buddhist, perhaps he'd say "huh?". I can explain the story of Christ to him, and he might at second remove grasp the significance of The Cross in a picture. It's not gonna make him a Christian, though. Maybe he'll convert someday, maybe some day he'll "get" the picture in that way. But explaining it, while helpful, isn't going to make him "get" it in that cultural, visceral, way.
This picture is also substantially outside TPF's norms.
If you don't get it, that's cool. I don't mind, and I appreciate your remarks. It's all good input, and helps me understand how broadly or narrowly appealing my picture is.
