A serene underwater portrait with floating curls, shimmering golden caustic light.

"A striking underwater portrait of a young man floating upright with his eyes gently closed and a calm, serene, meditative expression. His thick, voluminous black curly hair drifts upward and outward in the water, with small air bubbles clinging to the strands. He has a full, dense black beard and mustache, and small sparkling stud earrings in both ears. He wears a thin, sheer white button-up shirt, open at the chest, with the translucent fabric billowing and floating around his shoulders and collar. Dappled sunlight from the surface creates shimmering caustic light patterns across his face, neck, and chest, in golden-white ripples. The water is a deep teal-blue with tiny suspended particles and bubbles rising near the top of the frame, where the water surface is visible. Ethereal, dreamlike lighting, a rich palette of teal, deep blue, and warm golden skin tones, natural skin texture, high detail, cinematic fine-art underwater photography, shot with an underwater camera housing, vertical 9:16 aspect ratio, close chest-up framing, sharp focus on the face." Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
