The photo above showing dense fog around the base of the Eiffel Tower, in Paris, France, was taken on December 17, 2007. When relatively warm, moist air overrides a cooler surface, "pea soup" fog may result. Fog is more commonly observed in autumn and winter when nights are longer and the surface has more time to cool. Dense fogs such as the one shown above can wreak havoc with a city's transportation network and render the appearance of its loftiest skyscraper or tower to be that of a structure having a much smaller stature.

Photo details: Canon EOS 350D camera, 100 ISO, 1.6 second exposure, Sigma 70-300mm F4-5.6 APO DG Macro lens at 190 mm.
