Monochrome Gänsemarkt Tunnel, Hamburg Subway Architecture

Black-and-white, high-contrast photograph of Hamburg's Gänsemarkt U-Bahn station, focusing on the tunnel architecture. A long perspective along the platform reveals the repeating curved arches of the ceiling, tiled walls, and stainless steel handrails. Overhead fluorescent tubes cast crisp stripes of light and deep shadows, guiding the eye toward the distant tunnel and vanishing point. Include a lone traveler as a silhouette or subtle motion blur to convey scale. Use a wide-angle view (around 24mm), with fine details in the tunnel surfaces and a touch of film grain for a timeless, industrial mood.
