This is a three photo hand-held-panorama of Paris roof topsntaken from the top of Galerias-Lafayette. The top of Palais Garnier, the old Opera, is the prominent building on the right. I love the detail in the photo that the Nikon D800's resolution gives (However, some of that resolution is lost when uploaded.) and the roof top-sky convergence. Camera D800 with a Sigma 24-70mm f/2.8 EX HSM, ISO 100, f/9.0, 32mm at 1/500th of a second. Processed in PS and converted to B&W using Nix Silver Efex Pro.
