In this series of photos, the f/stop was gradually increased, letting less light through the lens and progressively darkening the exposure of the images.  The first image, set to a normal exposure, appears quite bright, although the red is quite weak and unsaturated.  The red hue of the phone box becomes increasingly dark and more intense through the higher f/stops.
