Bridge Over Troubled Waters

As I was walking alongside the Shropshire Canal near the village of Rowton, in Chester, U.K., I came to this lovely bridge. Walking under it, I noticed the stark contrast between the region illuminated by sunlight on the underside of the brickwork, and the shadow region beyond. Being a compulsive stone thrower as a child, I found that old habits die hard, and experimented with small pebbles cast into the shadowed water. As the ripples moved outwards from the splash point, they entered the sunlit region, and reflections from their profiles were cast onto the underside of the bridge. The position of this part of the bridge relative to the water was such that the reflections acquired an elliptical shape. Notice also how the discontinuity in the slope of the bridge causes a slight discontinuity in the slope of the ripple reflections on the wall. Photograph taken in late May 2012.
