Il Pozzo di San Patrizio. This place is quite special. Although it is a standard tourist destination, once inside your imagination may start running. This was built long ago to lead people and livestock down from the Orvieto plateau to the well and back. Quite ingeneously it is built as a double helix, much like the 1932 double spiral staircase in the Vatican Museum. This was done in order to prevent collision of herds. Today visitors have to go down and back as well. You can see people playing with being close together and yet so far apart. The light, come from a glass roof and from small bulbs, quickly changes with each round that you go. This image was made about halfway down, where the mixture of cold and warm light is in balance. I had no tripod, which would not be of much use anyway. Instead I leaned through one of the holes and pressed my camera against the wall for a 4 second exposure while at the same yelling back as well mannered as I could to my two boys who were shouting from the bottom of the well.
