Two centuries before anyone could fly, Braun and Hogenberg drew the cities of the world as if from the air. Their Civitates Orbis Terrarum — the first great atlas of city views — spans some five hundred and forty places, from Venice to Cairo to Mexico, each rendered in bird's-eye splendour with figures in local dress placed in the foreground (partly, it's said, to deter the map from military use). To hang one is to look down on a Renaissance city, walls and harbours and all, exactly as its own citizens wished to be seen.

Before a size goes on sale, the file is measured against it: pixels per inch at that size, how much of the picture a crop would lose, tone and sharpness. A size that fails is not offered, so there is nothing to choose wrong.
