The moment I saw flashes outside my window, I grabbed my 5D with 16-35mm 2.8L, remote and tripod. I wanted to create a time lapse, so each frame had to be fast enough shutter to allow enough frames, rather than low ISO and long shutter speeds. Each frame is ISO 400, f/13 at 5.6 seconds. The view is out my balcony in Fort Lee, NJ.
