Golden Hour, Underwater Elegance

A stunning cinematic underwater split-shot photograph of a beautiful young woman swimming in a luxurious outdoor pool, half (only face) above water and half submerged. She is in profile view facing right, eyes gently closed, serene and elegant expression, long wet dark brown hair flowing gracefully behind her and underwater. 

She wears a shiny metallic golden-yellow bikini with thin straps and side-tie bottoms. Sunlight dramatically pierces the clear turquoise water, creating beautiful caustic light patterns and god rays on her tanned skin and the pool floor. Air bubbles and light refraction visible underwater. 

Her right arm is extended forward in a smooth swimming motion, hand gracefully reaching, left arm trailing behind. Perfect body proportions, athletic yet feminine figure. 

Photorealistic, hyper-detailed, shot on 35mm film with shallow depth of field, soft natural sunlight, vibrant colors, golden hour lighting, National Geographic style photography, 8k resolution, masterpiece, best quality
