HDR shot of an arcade in Paris, "La Galerie Vivienne", built in 1823.
There are about a dozen of really beautiful arcades like this one in Paris, and each is different in something. I really like the ambiance in this particular one.
And, one more thing : the christmas tree is not photoshopped, it was really red like this 😉
