Generate Home Trading Desk Portraits

Photorealistic portrait of the subject from the waist up, seated at a clean home-office desk — dual monitors displaying stock charts and a trading platform softly out of focus behind, a notepad and pen on the desk surface, city view through a window to one side. The subject wears a crisp open-collar button-down shirt, looking directly into the camera with composed confidence. Warm desk lamp light from one side mixes with cool monitor glow from behind, creating a natural layered interior light typical of a home trading setup. Shot on Phase One IQ4 150MP with Zeiss Otus 85mm f/1.4, f/2.0 aperture, 1/200s shutter speed, ISO 400. Detailed shirt fabric weave and collar construction, monitor screen glow softly resolved behind, notepad surface and pen in the foreground. Skin with natural subsurface warmth under the desk lamp key, visible pores, realistic catchlights. Avoid any environmental effect on the subject's face, avoid plastic or airbrushed skin, avoid fog or haze, avoid text and watermarks. 4:5 aspect ratio.
