If you love natural way of life and if you rather like to watch green landscapes than watching some large settlements constructed of steel and glass then probably there are not much of modern cities which could be attractive to you. However, even those urban areas, so-called bunches of steel, glass and concrete, can sometimes look beautiful. The most of the world’s largest cities are really magnificent during the nights when all those city-lamps and electronic advertisements are giving them unique and glorious shine. One of such cities is San Francisco, in California. Here we collected a gallery of photos where you can see the attractive side of this colossal city. Those photos were made by respective professional photographer Simon Christen.
What’s happening over the horizon? Although the scene may appear somehow supernatural, nothing more unusual is occurring than a setting Sun and some well placed clouds. Pictured above are anticrepuscular rays. To understand them, start by picturing common crepuscular rays that are seen any time that sunlight pours though scattered clouds. Now although sunlight indeed travels along straight lines, the projections of these lines onto the spherical sky are great circles. Therefore, the crepuscular rays from a setting (or rising) sun will appear to re-converge on the other side of the sky. At the anti-solar point 180 degrees around from the Sun, they are referred to as anticrepuscular rays. Pictured above is a particularly striking set of anticrepuscular rays photographed in 2001 from a moving car just outside of Boulder, Colorado, USA.
