Jean-Baptiste Camille Corot – Evening on the Lake Part 4 National Gallery UK

The picture has something of this: water, reflection, river, landscape, lake, nature, outdoors, tree, sea, sky, ocean, seashore, dawn, fair weather, beach, placid, pool, bird.
Perhaps it’s a painting of a boat on a body of water with a tree in the foreground and another boat on the water with trees in the background.
