Nahaufnahme eines Artefakts eines Tiefseetauchers

Cinematic hyperreal close-up portrait of {argument name="character" default="an antique deep-sea diver in a weathered brass diving helmet"} holding {argument name="object" default="a dark mysterious square artifact"} directly in front of the face with intent. The object is centered and blocks most of the visor, appearing as a flat near-black charcoal square with a subtle vertical gradient, sharp clean edges, and no markings. Show the diver’s wet gloved hands at the bottom foreground, fingers curled around the artifact, with realistic skin/leather texture, droplets, grime, and specular highlights. The helmet fills the frame: aged bronze and blackened metal, round rivets, ornate circular side fittings, corroded seams, scratches, algae-like residue, and a glass porthole rim barely visible around the square. Illuminate the scene with {argument name="lighting" default="cold blue underwater light from the left with warm amber reflections along the brass rim"}. Add {argument name="atmospheric elements" default="suspended bubbles, drifting particles, and murky underwater haze"} throughout the frame. The mood is tense and enigmatic; any visible eyes behind the glass should convey {argument name="emotion" default="focused obsession and dread"}. Use shallow depth of field, macro-level detail, cinematic contrast, teal-blue color grading, glossy wet surfaces, volumetric underwater ambience, no text, no watermark, vertical 4:5 composition.
