This was taken with my Iphone using the Reheld app. I took the photo around 5 o'clock in the afternoon with lots of traffic but was able to do a long exposure of 30 seconds. I placed the photo on the curb on the road to support the phone so it could be held steadily for the long exposure. Then I edited the photo in Lightroom on my Iphone to convert the photo to black and white and bump the contrast.
I love the black and white theme on this photo it makes it pop more
