Forest of Fontainebleau, c. 1830, Detalj 6, NG Washing Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: tree, light, wood, landscape, fall, water, river, nature, reflection, sun, leaf, winter, fog, lake, dark, moon, fair weather.
Perhaps it’s a painting of a wooded scene with a man on a horse in the foreground and a man.
