Differential in the Brass Souq

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. Create a square 1:1 museum-catalog frame with a strong first read and a slower second read at exactly 2880x2880 pixels. Location: a brass-spinners' lane in an old Riyadh souq at early morning. Show them in a plain ash-grey winter traditional Gulf outfit, cuffs turned back once, hefting a heavy gear wheel in both open palms. Make one rigorous physical condition the conceptual engine: a bench differential whose spider gear carries the average of two cranked shafts, geared double to show their sum performs real mathematics through nothing but shaped matter and lawful motion. Explore where the boundary lies between a tool that helps and a mind that hides; direct expression and posture toward sober delight, never melodrama or ad-like confidence. Use an eye-level 85mm portrait perspective with honest depth of field and no distortion. Make the composition grant old machined wear the same dignity as their face. Render it as museum-grade mechanism portraiture built from historically accurate analog computers, brushed-brass materiality, honest documentary realism, and quiet patient editorial composition, using diffuse overcast daylight held to gentle contrast so engravings stay legible 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: the difference between a wiped surface and a clean one, faint tide marks on ceramic, and metal dulled unevenly by touch. 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.
