Professioneel LinkedIn-portret met donkere achtergrond

A polished studio head-and-shoulders LinkedIn profile portrait of a {argument name="subject gender" default="man"} centered in frame, facing straight toward the camera with a neutral, confident expression, cropped from the upper chest to just above the head. He has short {argument name="hair color" default="dark brown"} hair with a slightly textured top, visible ears, and light stubble beard along the jaw and chin. He wears 2 clothing layers: a dark charcoal tailored blazer over a plain white crew-neck t-shirt. The background is a deep black seamless studio backdrop with a subtle soft vignette and no visible props. Use professional corporate portrait photography styling, soft directional key light from above and slightly to one side, gentle rim separation on the shoulders and hair, realistic skin texture, sharp focus on clothing and neck, shallow depth of field, high contrast, clean premium retouching, natural color grading, and a modern executive-yet-approachable look suitable for a {argument name="platform" default="LinkedIn"} profile photo. Compose it symmetrically, minimal and elegant, with the subject isolated against the dark background, photographed as if with an 85mm lens in a high-end studio.
