Renoir’s rowers at their lunch on the Seine — three figures under a trellis, the river and a skiff behind, wine bottles and glasses still on the white cloth. The Impressionist afternoon at its most generous: the meal is over and nobody has moved. A faithful reproduction of a public-domain painting at The Art Institute of Chicago. The whole picture is dappled light, but the bottles on the table are painted plainly — the one still thing. The best lunches are the ones nobody stands up from.

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.
