Hyper-Realistic Underwater Snorkeling Portrait AI Image Prompt

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.

Prompt

Subject: Person in the image

Create a hyper-realistic underwater close-range portrait captured with a wide-angle action camera in a waterproof housing. The camera is very close to the Subject (≈0.5–1 m), positioned slightly below face level and angled upward, with wide-angle distortion emphasizing depth while keeping the Subject dominant.

Mid-shot to ¾ body framing. The Subject fills most of the frame, with face and upper body clearly visible. Schools of tropical fish swim closely around, some passing near the lens to create layered depth, with mild motion blur on fish closest to the camera.

Natural sunlight enters from above, producing bright caustic patterns on the Subject and surrounding water, strong highlights near the surface, and soft blue gradients below. Floating water particles are visible between the camera and Subject, with slight refraction distortion around mask edges and hands.

The Subject appears calm and relaxed, floating effortlessly with subtle body movement suggesting buoyancy and breathing through the snorkel.

A shallow coral reef is visible below, slightly softened by depth, while nearby fish remain sharper. The water surface shimmers above with gentle ripples.

Color behavior reflects natural underwater absorption: dominant blues and aquas, vibrant yellow and black fish patterns retained, and skin tones realistic with a slightly cool cast.

The image should feel like a real close-distance snorkeling travel photo intimate, immersive, and authentic.

Do not alter facial structure or identity. The Subject must remain 1000% identical to the reference image.
