ポートレート — セルフィー、屋外

Create an ultra-realistic outdoor smartphone selfie using my uploaded face as the identity 
reference. Preserve my facial identity exactly without changing my face shape, facial 
proportions, skin tone, hairstyle, hairline, beard density, eyebrows, eyes, nose, lips, smile, ears, neck anatomy, or body proportions. 

The subject is photographed from an extremely low angle with the smartphone held 
approximately 50–70 cm below the body and tilted almost vertically upward toward the sky, 
creating dramatic ultra-wide perspective distortion. The camera is positioned directly beneath the subject, making the extended foreground arm appear much larger while the face remains centered above it. 

The subject is standing naturally while leaning slightly forward over the camera, looking directly into the lens with a genuine cheerful smile showing the upper teeth. Eyes are relaxed with a friendly expression. 
The right arm is fully stretched upward above the head with the palm facing toward the camera. Fingers are naturally spread apart with a relaxed curve. A silver metallic ring with black stripes is worn on the middle finger. The opposite arm extends toward the phone and occupies the lower foreground with realistic wide-angle distortion. 

The subject wears a loose black full-sleeve button-up shirt featuring beige tribal and geometric woven horizontal patterns. The top two buttons remain open. Sleeves are casually rolled near the wrists. A thin gold chain necklace is visible around the neck. The wrist holding the camera wears black, white and red thread bracelets. 

Hair exactly matches the uploaded reference image: thick dark-brown textured hair with medium volume, slightly messy, softly lifted by the breeze, natural side-swept fringe, visible individual strands, realistic flyaway hairs, identical hairline and density. 
Facial hair remains naturally light with a neatly trimmed mustache and jawline beard exactly 
matching the reference. 

Lighting is intense natural midday sunlight. The sun appears inside the lower-left portion of the frame, producing realistic starburst rays, optical lens flare crossing diagonally over the face, bright rim lighting around the hair, subtle warm highlights on the skin, realistic shadow beneath the chin, HDR exposure, accurate dynamic range, and physically accurate sunlight scattering. 
Background consists of a vivid deep blue summer sky covering nearly the entire frame with several large fluffy white cumulus clouds. Small palm leaves enter from the upper-right corner. 

Atmosphere is crystal clear with excellent visibility. Captured using a flagship smartphone ultra-wide camera (13 mm equivalent), HDR enabled, f/2.2 aperture, ISO 25, 1/4000 s shutter speed, autofocus locked on the eyes, ultra-sharp facial 
details, realistic optical distortion, natural perspective, true smartphone computational photography, photorealistic, 8K, highly detailed, premium mobile photography.
