Corot, Jean-Baptiste Camille – Landscape with a boy in a white shirt Hermitage ~ part 06

The picture has something of this: water, river, nature, landscape, tree, outdoors, lake, grass, reflection, pool, summer, environment, wood, flora, flood, sky, recreation, park.
Perhaps it’s a painting of a man standing in a field next to a body of water with trees in the foreground and a house on a hill in the background.
