Robert Walker's photographs are characterized by their bold colours, jarring juxtapositions of subject matter, and cubist compositional style. He works in full sunlight; clouds barely, if at all, appear in his photographs making the world, from the glaring white of pavement to the shadowy interiors of greasy spoon diners, an experience of being intensely seen and revealed. His vision of the city presents the individual caught up in a barely contained chaos where the boundaries between the real and imagined - advertisements, graffiti and window displays - blur. The artist also uses a large depth of field to show both near and far objects in sharp focus. Through such an approach, the cityscape is depicted as a confrontational arena, a space within which desires, impulses, beliefs and values clash. To heighten the frenetic activity of city life, Walker will often fill pictorial space with advertising, buildings, neon signs and people either gazing or walking in different directions.
