Art gallery, Rome
Nobody seems to know what this photo is about, so I'll explain: It's an art gallery, and art is about form and colour and composition; it's also about artifice and the artificial. So everything here is straight lines and right angles and squares and rectangles - except the man. He's the only organic form. As if to underline this, there's the half-circle of the door-push in centre-screen - an artificial analogue of the rounded forms of the organic world. Simple, really.
