Candid Black-and-White Outdoor Beach Portrait of Young South Asian Man in Unbuttoned Linen Shirt and Aviator Sunglasses

An Ultra HD, HDR, fine-art black-and-white photorealistic vertical medium-shot outdoor portrait photograph strictly preserving the exact visual identity, facial geometry, body proportions, and calm, confident 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 sharp jawline, rounded chin, natural warm fair-to-wheatish skin tone rendered in rich monochrome tonal gradations with fine, realistic skin texture and visible natural pores. He turns his head in three-quarter profile looking toward the right through stylish dark black flat-top aviator/navigator sunglasses with dark tinted lenses. He features neatly defined dark arched eyebrows visible behind the top bar, a straight prominent nose bridge, and a well-groomed, neat short dark boxed beard connecting cleanly along his jawline and chin with a trimmed mustache along his upper lip, resting in a composed, calm closed-mouth neutral expression on naturally contoured lips. His thick, dense jet-black hair has a textured crop with natural wavy-curly volume swept upward and forward on top, paired with clean, tapered faded temples and sides. Around his neck hangs a thin silver chain necklace featuring a circular pendant ring. He is dressed in a breezy, casual coastal resort outfit: a relaxed-fit, lightweight crinkled white linen/cotton long-sleeve button-down shirt with a mandarin/band collar, worn unbuttoned deeply down the chest to reveal natural chest contours, featuring a left chest patch pocket and sleeves casually rolled up past the forearms. He poses in an effortless, candid outdoor posture: leaning his torso slightly forward with his right hand resting casually in his pocket or behind his back, angled in three-quarter profile while gazing thoughtfully off-camera. The setting is a tropical outdoor beach or coastal landscape: directly behind him is a soft-focus background of tall swaying coconut palm trees and a sandy beach path dissolving into creamy, smooth bokeh under open-sky coastal ambient daylight. Lighting is soft, natural diffused daytime coastal daylight, casting clean specular highlights across his dark hair strands, facial contours, neat beard, linen fabric texture, and necklace pendant, balanced by deep, rich contrast and smooth grayscale gradients. Captured in monochrome with an 85mm portrait prime lens simulation at f/2.0, tack-sharp optical focus on the subject, creamy background bokeh, authentic black-and-white tonal depth, 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.
