Looking at the cityscape, I saw a space between land and clouds where the corporate offices sat, but also between urban and urban. In between my residential neighborhood, where I stood to get this shot, and the downtown highrises was this rural patch of land, a farmer's field.
I like looking for these types of exceptions to the landscape. What is unique? What makes this interesting? How does this present in the viewfinder? All of these questions that run through my mind help me with composition.
