Jean-Baptiste-Camille Corot, French, 1796-1875 – Pollard Willows Philadelphia Museum of Art

The picture has something of this: tree, landscape, cavalry, mammal, outdoors, fog, wood, cropland, farm, daylight, mist, dawn, agriculture, nature, sky, grass, people, light.
Perhaps it’s a painting of a wooded scene with a man and a dog in the foreground and a woman in the background.
