Architecture winner: Concrete Circle by Tim Cornbill, UK. "Having just arrived in Berlin on a bright summer's day, my wife and I decided to take a morning walk along the River Spree. We soon came across a large concrete building, and I was immediately struck by its geometry and scale. Across the river, I positioned myself for a single point perspective and waited for the right moment to capture it. A couple came into the viewfinder and I noticed the cyclist out of the corner of my eye. I waited for them to move into the frame and hit the shutter to try and balance the composition." (Photo/CFP)
