I am fortunate enough to sit at my desk and look out at the Arno from my window. Much of the time, I just glance at the Arno when I'm not looking at my computer. At other times, I look up at the Arno and contemplate its color: sometimes it's a murky green and other times a darker grey. A few hours ago, I was working on my computer and when I looked up, I was enchanted by all the colors. I felt impelled to grab my camera and take a picture.
