Ultra-photorealistic 8K RAW DSLR photograph, underwater swimming pool scene, crystal clear blue water with subtle light caustics and tiny air bubbles rising, bright pool lighting from above creating soft volumetric god rays and shimmering reflections on the mosaic tiles. Subject: A stunning young woman with exact same facial features, skin tone, bone structure, and identity as in the reference image [attach the provided photo as reference], 100% identical face, do not alter face, eyes, eyebrows, nose, lips, or smile. Long voluminous dark black wavy hair floating naturally in the water, strands gently drifting around her face and shoulders. Beautiful smile showing teeth, confident and playful expression, subtle water droplets on skin, realistic wet skin texture with visible pores, natural skin imperfections, and realistic underwater light refraction on her body.
