Vintage sepia portrait of a man with messy hair and round glasses, leaning on a wooden railing

Prompt

Create a sepia-toned vintage photographic portrait of a middle-aged intellectual man leaning forward on a rough wooden railing, shown from the chest up in a three-quarter view facing left. He has a weathered face, deep forehead lines, a serious contemplative expression, messy windblown light hair, and small round wire-rim glasses. He wears a loose white linen shirt with rolled sleeves and an open collar, slightly wrinkled and sunlit. His forearms rest across the rustic railing in the foreground. Use dramatic natural light from the upper left, with the face partly illuminated and the background falling into deep black shadow, suggesting an outdoor porch or rural setting. Render as an early 20th-century sepia gelatin silver or albumen print: warm brown monochrome tones, high contrast, soft focus at the edges, visible film grain, dust specks, scratches, vignetting, uneven exposure, aged paper texture, and slightly faded archival wear. Composition should be intimate and documentary, with the subject placed slightly right of center, large dark negative space behind him, no modern objects, no text, no watermark.
