男子形象——淡水水下洞穴

Ultra-realistic cinematic underwater photograph of a young adult muscular man sitting cross-legged on the rocky floor of a deep natural underwater cave, recreating the reference image as closely as possible in composition, pose, framing, proportions, lighting, atmosphere, color palette, and photographic texture.

SUBJECT:
A young adult man with a muscular, naturally athletic physique, broad shoulders, defined arms, strong legs, and realistic masculine proportions. Short-to-medium dark brown hair floating naturally underwater, slightly messy and swept upward by the water. Light-to-medium skin tone with realistic underwater skin texture. Short natural beard/stubble, defined jawline, straight nose, and natural facial features. His head is tilted upward as he calmly looks toward the surface above, with a peaceful, meditative, introspective expression.

POSE:
The man is seated cross-legged on the underwater rocky floor in a relaxed meditation-like posture. His torso is upright and centered. Both arms rest naturally beside his knees, with his hands relaxed and fingers slightly curved. His legs are crossed naturally in front of him, with realistic anatomy and proportions. The pose should feel completely natural and weightless underwater.

CLOTHING:
He wears a simple dark olive-green/black sleeveless athletic tank top, slightly loose and naturally floating with the water. The fabric appears darker and subtly translucent in places because of the underwater lighting. No unnecessary accessories.

ENVIRONMENT:
A deep, mysterious freshwater underwater cave or rocky cavern surrounds him. Large irregular natural rocks and boulders fill the background and foreground, covered with subtle aquatic vegetation and moss. The water is deep blue-green and slightly murky, creating atmospheric depth. Small aquatic plants and stones are visible around the man's feet. The environment feels ancient, quiet, isolated, and otherworldly.

LIGHTING:
Strong natural sunlight penetrates the water from the surface directly above, creating dramatic volumetric shafts of blue light descending through the dark water. A concentrated beam illuminates the man's face, shoulders, arms, and parts of the rocks while the surrounding cave gradually disappears into deep shadows. Tiny suspended particles and streams of air bubbles catch the sunlight, producing sparkling highlights above his head. High contrast between illuminated areas and dark underwater shadows.

COMPOSITION:
Vertical portrait composition, approximately 2:3 aspect ratio. The man occupies the lower-middle portion of the frame, centered almost perfectly. Leave a large amount of dark open water above his head, emphasizing the depth of the cave. His face is positioned around the center of the image while his crossed legs extend toward the lower foreground. The camera is positioned slightly below or at approximately chest level, looking subtly upward toward him and the water surface. Maintain the same balanced symmetrical composition and spacious negative space as the reference.

CAMERA:
Professional underwater cinematic photography, full-body portrait, realistic perspective, approximately 28–35mm lens, medium-wide field of view, natural perspective, moderate depth of field. The subject remains sharply detailed while distant rocks gradually soften into atmospheric darkness.

VISUAL STYLE:
Ultra-realistic cinematic photography, premium feature-film underwater cinematography, natural human anatomy, physically accurate underwater lighting, realistic skin and fabric textures, subtle film grain, soft photographic contrast, rich blue-green color grading, deep blacks, muted highlights, atmospheric haze, suspended particles, realistic caustic light patterns, subtle underwater distortion.

DETAILS:
Individual strands of hair floating naturally in the water, tiny air bubbles rising above the man's head, realistic skin pores, wet skin highlights, subtle tattoos on the upper arms if naturally visible, detailed rocks and aquatic vegetation, tiny particles illuminated by the sunbeams, realistic water diffusion and light scattering.

MOOD:
Silent, mysterious, spiritual, meditative, powerful, isolated, dreamlike, and cinematic. The image should feel like a still frame from a high-budget underwater adventure film while remaining completely photographic and believable.

NEGATIVE PROMPT:
cartoon, CGI appearance, 3D render, plastic skin, artificial anatomy, distorted hands, extra fingers, missing fingers, deformed legs, duplicated limbs, exaggerated muscles, floating body parts, incorrect cross-legged pose, unnatural hair, oversaturated colors, excessive sharpness, artificial lighting, studio background, swimming pool, modern objects, scuba equipment, low-resolution, blurry face, distorted face, unrealistic water, excessive bubbles, fantasy creature, text, watermark, logo.
