On Saturday my brother and I went to Brooklyn for a day trip. We visited Governor’s Island and walked around Brooklyn. The sunset was at 830 pm and I wanted to do a day to night timelapse of the city from Brooklyn with the sun setting over the buildings. I was at the iconic Brooklyn Bridge Park with the piers overlooking the skyline. I got there about 7-715 pm and started taking photos with 6 second intervals. 
On a side note, I was closer to the water as the sun was going down originally but a security guard kicked off about 10 photographers to the walkway. Oh well, I still thought there might be some awesome color as the sun went down and it didn’t disappoint.
I was shooting in manual exposure with my 28 mm f/2.8 prime lens using my Nikon D7100. My original exposure was f/13, ISO 400, 1/125 seconds. I took close to 850 photos until 915 pm (45 minutes after sunset). The clouds and colors were amazing. The reflections of the water were simply stunning!
I kept shooting after the sun went down to capture the lights turning on in the skyline. My exposure was eventually 5.0 seconds at ISO 800. I started to ramp the ISO higher towards the end because I had a 6 second interval and need at least a 1 second buffering time in-between photos.
All my editing was done with LRTimelapse, Lightroom, and Adobe Premiere Pro for some minor warp stabilization since I bumped the camera a little bit during one of my shutter speed adjustments.
Overall this turned out perfect (minus the security guard) but lesson learned make sure you are in a spot you won’t get kicked off if you are going to be there for a long time.
Hopefully you enjoy the video and happy 4th of July!
