Paddlewheel Steamboat on River with Sharp Fog Line

Soft overcast light from just after sunrise illuminates a paddlewheel steamboat moving along the river near Obninsk. The vessel sits in calm water under a pale midsummer sky. A surreal condition dominates the lower third of the view: thick fog fills the space up to a knife-sharp horizontal edge. Above this abrupt line, the air remains clear and humid from recent rain. The steamboat's wooden hull and metal wheels appear in sharp detail against the water. The paddlewheel turns slowly, churning the liquid surface while the fog remains perfectly still beside the boat. The water reflects the pale sky above the fog line. A small wave breaks against the metal railing, scattering droplets that catch the diffused morning light.
