Natural Outdoor Realistic DSLR Portrait

Transform the uploaded photo into an ultra-realistic outdoor portrait while using the uploaded image as the only identity source. Preserve the person's facial identity exactly, including face 
shape, proportions, skin tone, skin texture, pores, eyes, eyebrows, eyelashes, nose, lips, ears, beard, mustache, hairstyle, hairline, hair density, texture, strand direction, flyaway hairs, and body proportions. Do not beautify, alter, or regenerate any facial or hair features. 

Capture in 4:5 portrait (1080×1350) using a flagship smartphone rear camera with a 3× 
telephoto lens (70–77mm equivalent). Camera positioned 2.3m from the subject at 1.4m chest height, perfectly level with no tilt. The subject stands slightly left of center, occupying about 58% of the frame. Body rotated 20° right, head turned 15° back toward the camera, relaxed shoulders, weight on the left leg. 

The subject smiles naturally with slightly parted lips and visible upper teeth while maintaining direct eye contact. The right arm is extended naturally with the right hand gently resting on a vertical wooden slat pillar. The left arm hangs relaxed with slightly curled fingers and wears a simple black wristband. 

Wear a light mint-green oversized linen button-up shirt with sleeves rolled below the elbows, top two buttons open, paired with light-wash blue jeans. Preserve realistic linen texture, wrinkles, folds, stitching, and natural fabric drape. 

Scene: a modern villa courtyard with a white contemporary building, dark window openings, grey stone lower wall, interlocking stone pavement, ornamental areca palms beside the subject, and a vertical wooden architectural pillar on the right. Background features natural optical 
portrait blur. 

Lighting is bright natural afternoon sunlight from the upper left, producing soft facial illumination, gentle jawline shadows, accurate skin texture, balanced HDR highlights, natural colours, and premium smartphone computational photography. 

Camera Settings: Flagship smartphone, Portrait Mode, 3× telephoto, f/2.8, ISO 32, 1/1600s, HDR enabled, eye autofocus, optical background blur, ultra-photorealistic, 8K.

Replace only the identity with the uploaded person's identity while preserving the uploaded hairstyle exactly.
