Generate Great Barrier Reef Selfies

Photorealistic environmental selfie taken underwater in the Great Barrier Reef, arm's-length phone-camera framing, subject wearing swimming goggles, vivid coral formations and tropical fish filling the background in turquoise and gold light. Sunlight refracts from the surface above into god-ray beams cutting through the water column. Wide-angle 24mm selfie perspective, f/2.8, 1/1000s, ISO 100, Sony A7R V simulation. Slight edge distortion consistent with a real waterproof phone camera. Skin visible through the mask showing natural pore detail and subsurface warmth, realistic eye detail behind the lens glass, fine hair floating freely. Kodak Portra-style grading — warm highlights, clean cool blues in the water, balanced saturation. Subtle chromatic aberration on high-contrast coral edges, fine sensor grain. Avoid cartoon styling, avoid plastic skin, avoid extra fingers, avoid warped anatomy, avoid flat lighting, avoid text or watermarks. 2:3 aspect ratio.
