荒れ狂う嵐の海を前に、灯台守がフレネルレンズの手入れをする

A breathtaking, ultra-detailed masterclass artwork capturing a weathered, gray-bearded lighthouse keeper inside the high lantern room during a violent ocean storm. The keeper wears a dark oilskin wool peacoat and brass-buttoned vest, carefully maintaining a massive, intricate Fresnel lens made of polished brass and cut crystal prisms. The central lamp beam radiates intense golden volumetric light rays, cutting through dark tempestuous night fog. Outside the glass panes, towering dark ocean waves smash violently into spray. Dramatic chiaroscuro lighting, tactile wet coat and polished metal physics, definition of High Visual Impact and Technical Skill, 8k resolution, masterpiece.
