Key instructions to preserve
No beautification, no face reshaping, no expression change unless stated.
GuardrailThe mosaic must be recognizably the subject at full viewing distance.
IDENTITY LOCK: Use the uploaded photo as the sole identity reference. Preserve the subject's facial structure, skin tone, eye shape, hairstyle, and every distinguishing feature exactly — the person must remain instantly recognizable. No beautification, no face reshaping, no expression change unless stated. SCENE: A grand public mosaic of the subject installed in a vaulted civic space — a fictional equivalent of Grand Central Terminal or a European train station — the mosaic occupying the full end wall of the concourse, passengers streaming below providing human scale. PHYSICS & CRAFT: Hand-laid glass and stone mosaic tesserae — individual tiles visible at close range, the image resolving into a recognizable portrait at the full scale of the wall. The golden Byzantine-style gold-leaf tesserae in the halo- like background catch the vaulted station's skylight at 6000K. The commuters beneath are lit by a mix of skylight and interior 3500K station lamps. TECHNICAL EXECUTION: 24mm f/8 from the concourse floor, the full mosaic wall visible with the arched ceiling above it, commuters in the foreground blur, the scale contrast between human figure and monumental mosaic is the primary drama. HARD CONSTRAINTS: The mosaic must be recognizably the subject at full viewing distance. Do not replicate the specific interior of any real named landmark. Maintain the Byzantine mosaic tessellation style.
