Architectural photography, landscape 4:3. A modern riverside library at dusk in early winter: a low horizontal building with a full glass facade, warm golden light glowing from reading rooms inside, rows of bookshelves and silhouetted readers visible through the glass. A wide stone riverside promenade with bare plane trees leads toward the entrance in the foreground, the calm river reflecting the building lights and the deep blue twilight sky. Shot on a 24mm lens from a slight low angle across the promenade, straight vertical lines, layered depth from promenade to facade to river, crisp concrete, glass and stone materials, cool blue dusk against warm interior amber, no text, no logos, no people in the foreground, no watermark.
