Forest of Fontainebleau, c. 1830, Detalj 2, NG Washing Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: water, tree, landscape, river, rock, nature, light, outdoors, fall, park, wood, environment, leaf, scenic, waterfall, reflection, mountain.
Perhaps it’s a painting of a river in a wooded area with rocks, trees, and a person standing on the side of the river looking at the water.
