Photorealistic waist-up portrait of a young man standing outdoors

Photorealistic waist-up portrait of a young man standing outdoors in a park with a soft green bokeh background, shot at eye level in natural soft daylight, warm cinematic color grading. He has thick, dark hair swept back, a neatly trimmed short beard, expressive deep brown eyes looking directly at the camera with a calm, confident expression. He wears a white crew-neck t-shirt under an open black button-down shirt with sleeves casually rolled, a black modern wristwatch visible on his raised hand as he runs fingers through his hair. Centered composition, shallow depth of field, crisp detail in the eyes, lashes and facial hair, smooth natural skin texture, subtle catchlights, gentle soft shadows and warm highlights on the face, slight vignette for focus, high resolution, realistic lighting, cinematic film look, soft contrast, accurate skin tones, no heavy retouching, stylish contemporary portrait. 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.
