Jean-Baptiste Camille Corot – The Wood Gatherer Part 4 National Gallery UK

The picture has something of this: nature, tree, landscape, water, fog, river, mist, wood, park, smoke, outdoors, lake, light, environment, leaf, grass.
Perhaps it’s a painting of a man sitting in a field next to a tree and another man standing in the distance with a dog on the other side of the painting.
