Doors & Windows of Pittsburgh

I started a new side project yesterday afternoon. My goal was to shoot something new and different. I challenged myself by setting rules to follow.

Rule #1 ~ Only one snap of the shutter per composition.
Rule #2 ~ Only one hour to produce (create something new) work in.
Rule #3 ~ ISO had to stay at 200 and f/stop needed to stay at 2.8

You can see the complete hour of shooting (HERE). When I started out on my walk to do this project I had no idea what I would do.
