Hyper-Realistic Underwater Snorkeling Portrait

A detailed prompt for generating a hyper-realistic underwater close-up portrait, mimicking a wide-angle action camera shot. It specifies the composition (subject dominant, schools of fish creating depth), lighting (natural sunlight with caustic patterns, blue gradients), and technical details (wide-angle distortion, visible water particles). Crucially, it requires the subject's identity to be 100% identical to a reference image, making it suitable for personalized travel or adventure content.
