Wow!
Back in '79, as a class assignment for a university class I travelled into the city to take photos of the Chrysler building's interior and exterior. I borrowed my dad's Nikon camera to perform this task.
As I entered the main elevator lobby of the Chrysler building, I took out the camera to take some photos. A security guard immediately pulled me to the side and confiscated my camera. I was then escorted up to one of the top floors to a patent attorney's office and read the riot act. Fortunately for me, once I explained the task I was assigned, he offered me several glossy photo books on the design and construction of the tower and instructed the security officer to return my camera as I exited the building. The professional glossy documents were not accepted for credit with the assignment, excuse denied. I only received credit for the written portion of the assignment and never received the glossy material back. Harumph.
