Prompt
A real photograph in the fine-art genre, captured on fine-grain black-and-white film with a normal lens and measured depth of field, slight silver grain holding subtle material detail, a disciplined silver-gelatin tonal range. The underside of a concrete road bridge seen from the dry riverbed beneath: massive piers, a ribbed soffit with repeating beams, a shaft of daylight at the far end, a thin stream and rounded stones in the foreground.
Light: one broad, softly raking light enters from the left end under the span, tracing a quiet rhythm of illuminated beam edges and long gentle shade, luminous highlights on the wet stones and the piers; restrained midtones, articulate deep greys and a deep black at the bridge's centre; the repeating beams converge toward the bright end.
Wide 16:9 frame. No people, readable text, signs, numbers or logos.
