I was in Philadelphia for a trade show for work few weeks ago. On the 19th floor of one of downtown hotels, I was waking up each day to observe the sunrise. Or more like the sunbeams hitting the top floor windows of the adjacent office building (on the right). Already on the first day, by the time I had breakfast and hit the sidewalks, I had an idea what I wanted to photograph in Philadelphia. See below a small gallery of my favorites.
