City walls, especially the walls of commercial buildings, are a kind of canvas that are worked on by multiple authors. Sometimes the authors are in conversation with each other, as with the graffiti writers and those who remove it. Often the walls are used to communicate some message – often prohibitory, sometimes declarative, occasionally persuasive. Time and light are authors. In one image a dialogue can be created between bureaucratic signs, street art, shop keepers signs, surface texture, colour, materials, colour, light and shadow. The dialogue is captured and created by the parameters of the frame – the components of the dialogue preexisted the photograph but were not necessarily in conversation, or relation, with each other.
