A few days later we pay him another visit. He has been busy in our absence; the picture looks to us to be finished, and we begin to compare it with the natural scene in front of us. In nature those trees on the right stand so sharply against the sky that we can count their branches. Evidently the artist hasn’t, for in his picture he has left out a great many of them; indeed, he has put in only a few of the more prominent ones. See, too, how he has painted the trees; he hasn’t put in a single leaf. Instead he has represented the foliage in masses, lighter in some parts where the sun strikes, darker in the shadows. When we compare his trees with the real ones, they are not a bit the same, and yet the painted ones look all right; we can see at once that they are maples and in a general way very like the real ones.
