Karl Friedrich Schinkel (1781 – 1841) – Morning Alte und Neue Nationalgalerie (Berlin)

The picture has something of this: tree, landscape, water, nature, outdoors, sky, wood, dawn, sunset, sun, summer, daylight, light, grass, park, beach, recreation, leaf.
Perhaps it’s a painting of a wooded area with a group of people sitting on a bench in the foreground and a view of a body of water in the distance.
