I really like photographing LA at night. Like any big city, it has it's share of obscure nooks and cul-de-sacs, places where the streetlights don't penetrate, but seldom a view of the sky. In the case of rooftops, not only is the lighting spare, but you can really see the sky, sometimes from horizon to horizon.
Tonight the sky was especially fine.
