Ha! But do you see what I mean? There seems to be a grayish shadow or silhouette, around the edge of the buildings on the Right (which also goes in front of the lamp post), and that also happens on the other side of the street on those buildings. It is not the color of the rest of the sky. It looks like leftovers of a layer that didn't get cleaned up, and it seems to follow the contour of the buildings. If that is pollution that is awful and it really chose an awful path to appear on your photo!
Awesome picture anyway!
