Generate Serene Underwater Portraits

A serene, hyper-realistic underwater portrait. The subject is submerged, floating effortlessly. Their hair is suspended in the water, fanning out in a weightless halo around their head. Sunlight from the surface pierces the water, creating dancing caustic light patterns on their face and neck. The expression is calm and peaceful, eyes open. Bubbles cling to the skin. Technical Specs: Captured with a Phase One IQ4 150MP (Housing), 35mm lens. Shutter 1/500s. Real fluid dynamics: The hair movement is fluid and organic. The light rays refract realistically through the water surface. Skin texture is magnified slightly by the water. 8K resolution, fine art aesthetic.
