I get to work early to avoid traffic (I'm usually in my office around 7:30am), and twice a week during semester I have 8am classes to teach, so the uni is always nice and quiet when I arrive. Later in the day, most of these places are packed.
WOW!!!! That totally screams silence! I can just imagine the serenity. And the campus is really nice at that time of the morning. Nice collage, especially the Gursky's and the light from the carpark. :)
When I was teaching, I always loved getting to school earlier than everyone else. I was wishing I could shoot an empty hallway like you did. These shots are great for the word silent-especially since schools are usually anything but silent! Great job!!
