Sergio Chiaramonte: This shot was taken at the end of a long visual inspection around the chemical industry north of Milan on a cold winter night.

We've collated some of our favourite photographic artists from the social network for you to enjoy. This busy freeway passes along the west side of the city, so look up when the sun sets and give yourself plenty of time to get downtown to watch the city turn gold and light up as the sun goes down. Photographing this site would require more than simply sneaking on site, snapping the picture and making a hasty retreat. As it turned out, they were Carabinieri wearing bulletproof vests, heavily armed with loaded machine guns.
