Prompt: “Edit the uploaded underwater photograph to reduce the blue-green color cast and recover believable detail. Restore skin tones and warm colors selectively according to depth, retaining the natural coolness of distant water. Gently reduce haze and backscatter while preserving fine textures, bubbles, and soft underwater light. Keep every person, animal, and reef feature unchanged. Avoid invented marine life, oversaturated coral, artificial sunbeams, or a dry, above-water appearance.”
