I'm working on a series for school based on the culture shock I have experienced moving to the city. Part of it was that I couldn't sleep for about a month after moving in, because the noise from the subway, the traffic, and the drunk students outside my window kept me from ever really getting into a quality REM cycle. I've spent quite a few nights over the last few weeks in this position. Maybe f5.6 isn't really a wide aperture, but DOF was a big part of this picture, so I think it qualifies.
