Tonight, New York will remember the lives lost on September 11th with the annual Tribute in Light memorial. The Tribute is a breathtaking art installation made of 88 xenon light cannons which shine from the shadow of the World Trade Center into infinity. The lights can be seen from 60 miles away. I've spent the last two September 11ths capturing images of the display. Here are some of the better images from the Brooklyn waterfront (2012) and Lower Manhattan (2013).
