The pedestrian avenue running through the More London offices between London Bridge and Tower Bridge. A slim metal line is set dead-centre into the granite, running the length of the walkway toward the river and catching gold in low sun: a perfect ready-made leading line, with glass towers reflecting each other on both sides.

Best time: early and late for backlight down the avenue and long shadows. Wet days, when the polished granite and the line both turn to mirror.

Look for: get low and put the line dead-centre, running to a backlit figure at the far end. Reflections and repeated verticals in the glass, and commuters reduced to silhouettes against the bright end of the avenue.
