Ultra-close low-angle smartphone selfie with sky background

A photorealistic, ultra-close low-angle smartphone selfie of a completely fictional 20-year-old Japanese woman outdoors beneath a bright summer sky. The camera is placed very low and aimed upward, creating an exaggerated wide-angle perspective where her bent knees dominate the foreground and naturally frame her smiling face above. She leans forward toward the camera with a cheerful, playful expression, looking directly into the lens with bright eyes and a relaxed genuine smile. Her dark brown hair is tied back in a casual ponytail with a few loose strands moving in the breeze. Vertical 9:16 composition, natural smartphone ultra-wide lens (about 20-24mm equivalent), camera positioned close to the ground. The face appears near the top center of the frame, while both knees occupy most of the lower foreground, creating strong depth and perspective. A vivid blue sky with scattered white clouds fills the background. Strong midday sunlight is the primary light source, with soft skylight providing cool ambient fill. Keep shadow detail visible without crushing blacks. Most skin remains naturally matte, with restrained highlights only on the forehead, cheeks, nose bridge, shoulders, knees, and light-facing planes. Hair has fine strand detail with subtle highlights only where directly illuminated. She wears casual summer clothing with a coral textured outfit visible between the knees. Fabrics show realistic weave, stitching, natural wrinkles, and gravity. Skin retains natural pores, fine hairs, and slight tonal variation. Natural smartphone HDR, slight handheld imperfection, mild lens distortion from the ultra-wide perspective, realistic digital sharpening, no beauty filter, no readable text, no watermark, no social-media interface, no logos.
