This shutter speed/aperture combination perfectly lit up the building yet preserved the detail of the scene. I started with twice the aperture, but I wasn't getting the crispness that I wanted in the architecture. Sometimes we make the mistake of shooting wide open in low light, but that often results in a loss of detail.
