Mark has said to me on more than one occasion, "symmetry is a tyrant," and he's certainly right about that! If you're not standing in EXACTLY the right spot when shooting architecture, things appear to be tilted. I can't tell you how much I've learned while getting these images through postwork. I assure you, this is perfectly, thoroughly, exactly lined up down the center line of the door, and it STILL looks like it's leaning a bit to the right. Shoot, I don't know. Maybe the whole danged building IS leaning a little to the right! LOL! This is on the Gold Coast in Chicago, across Lakeshore Drive from Lake Michigan. With a grand, impressive, two-story entrance like this, I would expect to see some rather grand, impressive double or triple doors. But no. One door, very modest. Perhaps this is the servant's entrance. Maybe it's just me, because I spent so long fiddling with this image, but that door seems a bit anticlimactic.
