An ultra-realistic documentary portrait of a weathered lighthouse keeper in a yellow raincoat, salt spray on his beard, squinting into the wind with a calm resolute half-smile, stormy grey sea blurred behind him. Tight vertical crop, cold overcast light with a hint of warmth on his face, deep authentic character in every line. National Geographic grade, extreme texture detail, 8k, no text.
