Candid Outdoor Portrait of Smiling Young South Asian Man in Red Button-Down Shirt and Sunglasses

An Ultra HD, HDR, photorealistic vertical three-quarter outdoor portrait photograph strictly preserving the exact visual identity, facial geometry, body proportions, and cheerful expression of the young South Asian man from the reference image, who serves as the primary visual identity reference. Maintain his authentic facial features: an angular oval-to-square face shape, defined cheek contours, clean jawline, rounded chin, natural warm fair-to-wheatish skin tone with fine, realistic skin texture and visible natural pores. He smiles candidly toward the right with an open-mouth grin showing neat white teeth on naturally contoured lips. He wears trendy semi-translucent dark grey/tortoiseshell square-frame sunglasses with tinted lenses, accompanied by neatly defined dark arched eyebrows, a straight prominent nose bridge, and a well-groomed, neat short dark beard connecting cleanly along his jawline and chin with a trimmed mustache along his upper lip. His thick, voluminous jet-black hair features a dense curly-textured crop styled with voluminous curls falling naturally over his forehead and temple with neatly tapered sides. On his right wrist, he wears a black leather strap bracelet/watch, and on his left wrist, a sporty black-and-silver circular chronograph wristwatch. He is dressed in a vibrant casual daytime outfit: a rich deep-red/crimson cotton long-sleeve button-down shirt featuring an open spread collar, unbuttoned top button, contrasting white buttons down the front placket, a subtle white embroidered script logo on the left chest, and sleeves casually rolled up to his forearms, paired with relaxed-fit black denim jeans. He poses in an effortless, candid outdoor posture: standing facing forward with his torso slightly turned, lightly hooking both hands along the bottom hem of his untucked red shirt near his waist, tilting his head slightly to his left while smiling warmly off-camera. The setting is an outdoor modern terrace/patio: directly behind him is a decorative horizontal wooden-paneled wall with warm brown wood-grain textures, topped by a black metal decorative privacy fence with geometric patterned lattice cutouts, set against softly blurred, lush green outdoor trees and foliage bathed in natural daylight. Lighting is bright, crisp, natural daytime ambient sunlight filtering through the canopy, casting clean specular highlights across his curly black hair strands, facial contours, neat beard, cotton shirt fabric weave, and watch details, balanced by smooth, authentic dimensional soft shadows. Captured with an 85mm portrait prime lens simulation at f/2.0, tack-sharp optical focus on the subject, creamy background bokeh, authentic vibrant natural color reproduction, and high dynamic range photographic realism in an elongated vertical portrait composition matching the original reference orientation. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
