After a long day at a conference, I joined several of my coworkers for dinner on the patio of a restaurant in Boston’s Back Bay neighborhood. We were all exhausted, but it had been a good day for everyone. I had brought along my camera to take some photos at the event, and just happened to have it sitting next to me at the dinner table. That’s when I looked up and saw the moon rising over the top of 111 Huntington in the background. The combination of blue hour twilight, the moonlit sky, and the distinctive roof of Boston’s “R2D2 building” made for an unforgettable photo.
