Unveiling the Cornstarch Demonstration — 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: a science-center demonstration hall before opening, its exhibits still sheeted. Show the subject in a slate cardigan over a pressed white shirt, folding one dust sheet back over their forearm. Build the artwork around this material rule: a wide steel tray of dense cornstarch suspension that carries their struck knuckles like pavement yet swallows their resting hand lets one quiet demonstration overturn an intuition older than language. Explore why a liquid is entitled to behave like stone when questioned rudely; direct expression and posture toward grounded wonder, never melodrama or ad-like confidence. Use a 90mm close-working lens: the fluid's response sharp near the frame's base and their attentive face readable above it. Make the composition anchor the brightest highlight on the material, never on them. Render it as quiet kinetic still-life portraiture built from genuine non-Newtonian samples, honest studio texture, believable hand-scale staging, and patient documentary framing, using cool window daylight from one side, balanced by a warm bench lamp and a palette of mud brown, brushed steel, and muted glass green. 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 rainbow slime aesthetics, splattered goo on skin, speaker-driven paint splashes, and ASMR dripping close-ups. No text, labels, logos, signatures, watermarks, random symbols, plastic skin, excessive bloom, or glossy AI finish.
