Catherine Jones, Bridge Street, Cambridge

Of course, it is the opportunity to photograph someone absorbed in what he is doing that gives me the desire to photograph. But the colours – the green of the gate, the blue of the jeans, the blue-green of the shop, and even the top and jeans of the woman walking towards me – helped bring it together. The name-board above the shop and the top and bottom bards of the gate lead away to the left, out of the shot. The man is leaning into that and that helps put dynamism into the shot because the sloping angles are set against the square verticals and horizontals.
