This is a shot from behind the clock on the top floor of the Musée d’Orsay looking at the Louvre across the Seine River. The Musée d’Orsay is converted from a railway station, hence the clock tower. I shot through plexiglass with my Zeiss 35mm f/1.4 wide open (at f/1.4) for absolute minimum depth-of-field so the landscape would be in focus but the foreground—the somewhat dirty plexi—would be out of focus and unobtrusive.
