Create an ultra-photorealistic outdoor summer selfie of the attached woman under strong midday sunlight, captured from a close, slightly low smartphone angle. She is facing the camera while squinting hard due to the bright sun, with one eye almost closed and her face slightly scrunched, creating natural expression lines around the nose and eyes. Her right hand is raised above her forehead to shield her eyes from the sun, partially casting shadow across her face; her fingers are visible with long, clean nails. She has red hair wearing it loose, with flyaway strands catching the sunlight. Her skin is white and sun-kissed with visible pores, freckles, mild redness on the cheeks and nose, realistic shine from sunscreen and sweat, and no makeup retouching or smoothing. She wears a minimal white bikini top with thin straps tied at the shoulders. The lighting is harsh natural daylight with strong highlights and crisp shadows, creating realistic contrast on the skin and shoulders. The background is a clear, vibrant blue sky with no clouds or distractions, reinforcing a hot summer, vacation atmosphere. Colors must remain natural and unfiltered, with realistic skin tones, bright sky blue, and no cinematic grading, HDR effect, or artificial contrast enhancement. The image must look like an authentic, unposed smartphone selfie taken outdoors, captured in true 4K quality, with realistic perspective, raw skin texture, natural imperfections, and zero visible AI artifacts or stylization.
