A single man watching a couple toss away their key on the "Padlock Bridge," Paris, by Ciana Pullen, 2014

There's been a tradition since about 2008 for lovers to attach a padlock to the railing of the Pont des Arts bridge in Paris, then toss the key into the Seine to symbolize eternal love. So many thousands upon thousands of padlocks hang off the railing in glittering clumps that authorities are removing the railing and replacing it with plexiglass in order to protect the bridge from undue weight, thus ending the tradition. As I was passing under the bridge I caught this man standing alone and watching a couple toss their key into the Seine.

While most tourists take boat tours down the Seine, a boat tour of the Canal St. Martin is a lesser known (and cheaper) but still very interesting thing to do in Paris. It will take you through the Seine and past the Île de la Cité and Île Saint-Louis, but turns off down the canal commissioned by Napoleon. You'll go through an incredible 19th century underground tunnel, a series of locks, and a beautiful neighborhood popular with more local Parisians than tourists. I took this near one of the locks to capture the perfect blue and black lines and shapes.
