Parted Dye Lines in the Flume Lab

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 fluid-dynamics teaching lab built around one long clear flume. Show the subject in a putty-colored lab coat open over a plain black tee, skimming the flume's surface with a clear acrylic straightedge. Build the artwork around this material rule: a fan of parallel dye lines between two close glass plates that parts around a steel disc and closes seamlessly behind it puts continuous motion through a form that never once looks hurried. Explore why the eye trusts glass more readily than it trusts obedient water; direct expression and posture toward gentle vigilance, never melodrama or ad-like confidence. Frame along the water's surface at forearm height so the flow's edge and their gaze share one plane. Make the composition give the dye's edge more acuity than any highlight. Render it as large-format hydro-engineering portraiture built from real channel flows, precise wet-metal detailing, truthful surface optics, and patient documentary framing, using cool diffuse daylight with a single warm practical reflected in wet metal and a palette of brushed steel, water grey, and one amber gleam. Photorealistic: this must read as a real photograph from a physical camera, never an illustration, painting, or 3D render. Resolve real surface detail: cotton that hangs by its own weight, seams that pucker very slightly, and collars softened by washing. 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 stock waterfall mist, whirlpool vortices, ripple-covered surfaces, levitating water spheres, and dramatic slow-motion splash photography. No text, labels, logos, signatures, watermarks, random symbols, plastic skin, excessive bloom, or glossy AI finish.
