Berlin staircase in black and white

I had the pleasure of spending a few days this past summer in Berlin -- a wonderful city in so many ways. I, of course, took a lot of pictures during my stay, but for some reason I never used my Canon 6D to photograph the square/spiral staircase of the hotel I was staying in. It wasn't until after I had checked out and called a cab that I thought to myself, you need to photograph that staircase before you go. With all my gear packed away and in a bit of a rush, I was only able to take three quick pictures with my iPhone 6 before my cab pulled up. While I regret not photographing the staircase earlier with proper gear, I'm still impressed by what our mobile phones can do in a pinch.
