The Eel Gatherers, c. 1860-1865, Detalj 5, NG Washingt Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: reflection, wood, water, texture, river, tree, abstract, light, nature, cave, leaf, vintage, wall, paper.
Perhaps it’s a painting of a person wading in a river in a wooded area with trees on either side of the water and a person standing in the middle.
