The 2015 Macy's Fireworks on July 4th 2015. These images were taken from the roof of a 35 story building near Tillary Street and the BQE in Brooklyn. It was like watching two different firework shows. To my left was the double barge near the South Street Seaport. To my right and going North were 3 barges near Midtown Manhattan. I was closer to Lower Manhattan, so I took most of the images in that direction. Using a tripod with a cable release and the shutter on the B setting and ISO 100 and F stop at F-16. I would trip the shutter and keep it open, while using black cardboard to cover the lens, until I got a bunch of bursts in the photo. I would then let the shutter close and take the next image the same way.
