During my daily lunch break yesterday, I went out and walked through the city center. I didn't get very far though. When you walk slowly and you start looking, you start seeing so much you don't need to go far.
I didn't have a focus when I came out of the building, but when I looked around me all I saw was bikes and their shadows.
A truck driver saw me take the first picture and he commented: "Taking photos of shadows?" He loved it!
