Generate Minimal Tech Desk Portraits

Photorealistic portrait of the subject from the waist up, seated at a minimal white desk — a slim open laptop, a smartphone, and two or three neatly arranged tech accessories on the surface behind, a clean white wall and small monitor stand softly visible in the background. The subject wears a plain fitted crew-neck T-shirt, looking directly into the camera. Large north-facing window to one side provides soft, cool, even daylight — the clean, clinical light of a product photography setup, minimal shadows, no warmth bias. Shot on Phase One IQ4 150MP with Zeiss Otus 85mm f/1.4, f/2.0 aperture, 1/200s shutter speed, ISO 100. Detailed T-shirt jersey knit texture, laptop lid material and keyboard surface softly resolved on the desk, clean desk surface with precise product arrangement behind. Skin with natural subsurface coolness under the north window light, visible pores, realistic catchlights. Avoid any environmental effect on the subject's face, avoid plastic or airbrushed skin, avoid screen glare, avoid text and watermarks. 2:3 aspect ratio.
