Man oh man, I could stare at this one for hours. I might have known another Stuck in Customs classic would come up. AN ABSOLUTE MUST SEE IN LARGE ON BLACK. I love twilight (and Maxfield Parrish paintings of it) and this has that kind of sky. This is a really senational moment captured here. Of course, the reflection on the sidewalk is an extra mesmerizing bonus. It's one of those rare shots that just adds something to your personal perspective on vision and perception. And the sense of history across two millenia here is tasteable--sad really because who could ever sack such a thing! Put Rome on my list of must go places.
P.S. - If you look at the large version again, you'll see an interesting HDR study in that that someone needs to replace a bulb on one of the the third floor archways and how the HDR processing handles the lack of light in that arch, and the sky beyond, as compared to the other lit arches.
