A warm, natural-light portrait of a relaxed young man

A warm, natural-light portrait of a relaxed young man leaning casually against a textured off-white stucco wall, three-quarter view from mid-thigh up, hands in pockets, slight head tilt and gentle genuine smile, neatly trimmed dark beard and thick, styled black hair. He wears a pale yellow linen button-up shirt with sleeves rolled to the forearms and light, tailored white trousers. Overhead a vine of bougainvillea with soft yellow and cobalt-blue blooms spills into the frame, adding organic color contrast. Soft golden-hour lighting, creamy pastel color grading, shallow depth of field (85mm equivalent, f/1.8) with smooth bokeh, subtle film grain, delicate highlights on cheekbones, natural skin tones, low contrast shadowing, warm midtones, slightly desaturated greens. Cinematic, friendly, approachable mood, high-resolution, sharp focus on the eyes, soft vignette, minimal retouching for authentic texture and linen fabric detail. 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.
