Fancy Photoshopping, not with anything added but much enhanced for maximum visual effect. Real or not is in the eye of the beholder. I would say not real because Brooklyn never looked so good.
Obviously fake, because in my experience I've never had to take a staircase to cross over that eastern tower of the Brooklyn Bridge.
Looks real enough, but I've never fully trusted those devious Brooklynites. When I lived there for a few years I didn't even trust myself. What could be up this photographer's sleeve?
I like the gray and russet bridge, with it's glorious tangle of cables, against the steely blue sky and skyline. It's quite evocative. Nice.
