Penyelam Antik dengan Artefak Kotak Gelap

Cinematic hyperreal close-up portrait of [an antique deep-sea diver in a weathered brass diving helmet] holding [a dark mysterious square artifact] directly in front of their face with intent. The object is centered, blocking most of the visor, appearing as a flat near-black charcoal square with a subtle vertical gradient, sharp clean edges, and no markings. In the bottom foreground, the diver's wet gloved hands grip the artifact with realistic leather texture, grime, water droplets, and specular highlights. The aged bronze helmet fills the frame with round rivets, ornate side fittings, corroded seams, scratches, and algae residue, with a glass porthole rim barely visible around the square. Lit by [cold blue underwater light from the left with warm amber reflections along the brass rim]. Surrounded by [suspended bubbles, drifting particles, and murky underwater haze]. The mood is tense and enigmatic; eyes visible through the glass convey [focused obsession and dread]. Shallow depth of field, macro-level detail, cinematic teal-blue color grading, glossy wet textures, volumetric underwater atmosphere.
