Create a 4:5 vertical portrait photography case titled "Young Developer Professional Portrait". Visual direction: clean desk, cool monitor glow, focused gaze, rational technical presence and young credibility. Subject requirement: a real ordinary male model, no celebrity likeness, natural facial detail, restrained but strong posture. Scene and composition: the image should feel like a complete commercial or editorial portrait, not an ID photo; keep the subject clear and make the background support the human story without irrelevant clutter. Lighting: large front-left softbox shaping the face, slight white-card fill on the right, natural shadow depth. Camera: 85mm portrait lens at f/2.8, sharp eyes, softened but readable environment. Color grade: low-saturation warm gray grade, natural skin, detailed shadows. Keep the result realistic and photographic, with natural facial features, skin texture, hair strands, wardrobe material, environmental light, and controlled depth of field. Avoid plastic skin, over-retouching, cartoon styling, AI artifacts, malformed fingers, and displaced facial features. Unless text is explicitly required by the visual direction, include no readable text, logos, watermarks, real brand marks, or unrelated platform UI.
