A ghostly old warship, pale and towering, is towed to her end by a squat, black, fire-belching steam tug — sail giving way to steam, the past to the future, beneath a sky Turner sets ablaze. The Temeraire was a hero of Trafalgar; here she goes to the breaker’s yard, and Turner turns her scrapping into an elegy for an entire age. Voted Britain’s greatest painting, it is a masterclass in how light can carry feeling: that molten sunset is the whole emotion of the picture. Progress, and everything it costs.

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.
