The Bioluminescent Cave Explorer

Create a photorealistic cinematic portrait of an adult male cave explorer standing inside an immense underground cavern. He wears a rugged expedition jacket, a practical headlamp, and a small exploration backpack. Luminous turquoise mineral formations glow from the cave walls, illuminating his face and reflecting across shallow pools of water. Tiny mineral particles shimmer in the air. His expression shows wonder and concentration. Emphasize realistic rock formations, believable wet surfaces, detailed expedition clothing, natural skin texture, dramatic atmospheric depth, science-inspired adventure photography, 8K quality, no text, no watermark. 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.
