Man, we love looking back at pictures and re-seeing them through new edits. We love the color of city lights, but a beautiful black and white moment also lived in this photo all along. There are reasons we deliver every image to clients in both color *and* black and white.
It can strike a subtly (or sometimes starkly) different tone, make for a very different album or collage to put together, or just show you images you've seen for years in a new way.
