One Slow Revolution — AI Portrait Prompt

Use the attached reference photo as the identity reference: keep the same face, skin tone, hair and features as the person in that photo, without beautifying, aging or altering them. Build a portrait 4:5 editorial artwork with protected negative space and a fully readable face at exactly 2560x3200 pixels. Location: an old lecture theatre with steep wooden seating and a demonstration bench. Show the subject in a brown herringbone jacket over a fine merino roll-neck, turning a demonstration handle one slow full revolution. Build the artwork around this material rule: a benchtop brass orrery whose stacked gear train holds every planet at tonight's true heliocentric position around a polished central sun shows how much of the world reduces to ratio and constrained motion. Explore why a machine with no memory chips can still remember mathematics perfectly; direct expression and posture toward attentive humility, never melodrama or ad-like confidence. Use a 90mm hybrid view: one machined detail near the lens, their readable face beyond. Make the composition keep every moving part inside the frame except one. Render it as gallery-grade technical realism built on lawful mechanism kinematics, precise engraved detail, tactile wood-and-metal textures, and emotionally intelligent portrait lighting, using cool north skylight fill with soft falloff into wood-paneled shadow and a palette of warm umber, pale vellum, and one muted teal accent. Photorealistic: this must read as a real photograph from a physical camera, never an illustration, painting, or 3D render. Resolve real surface detail: fine lint on dark fabric, water spotting on steel, and the soft rounding of edges that have been used for years. Keep one identity-locked person, credible hands and fingers, natural fabric, and coherent scale, contact, reflections, shadows, airflow, deformation, and materials. Background people only when essential, always secondary and clearly different. Avoid steampunk goggles, glued-on decorative cogs, glowing holographic overlays, impossible gear meshes, and clock faces. No text, labels, logos, signatures, watermarks, random symbols, plastic skin, excessive bloom, or glossy AI finish.
