A dignified adult lighthouse keeper in his late fifties stands in a weathered lighthouse doorway after a winter storm. He has a silver beard, a navy wool sweater, a dark weatherproof coat and a direct, thoughtful gaze. Frame a vertical chest-up environmental portrait with an 85mm lens and shallow depth of field, placing his face slightly off center. Sea mist and turbulent ocean remain softly visible behind him. Balance cool overcast daylight with a warm interior rim light. Emphasize tactile natural skin, wet fabric and wool detail in slate blue, charcoal, sea foam and muted amber. Museum-quality portrait photography, realistic anatomy, no text, brand marks or watermark.
