How the AI detective did

The AI placed its guess 64 km from the real location (it guessed Praia Grande, Macau).

A colonial garden terrace above a strait of junks — I choose Macau's Praia Grande across the estuary and date the albumen plate to 1878.

The evidence the AI read

• terrain: From a hillside garden the view falls to a deep-water anchorage ringed by steep bare mountains, with a far shore close across the strait. — A sheltered harbour squeezed between mountains and sea — a natural roadstead that made a small shore priceless to traders.
• architecture: Colonial arcaded blocks and a Gothic church tower stand along the waterfront below; a bandstand and a thatched pavilion sit in the terraced foreground gardens. — A young European colonial settlement laid out with public gardens on a subtropical coast.
• vehicle: The anchorage is filled with square-rigged sailing ships, and high-sterned junks thread between them; no steamer funnels dominate the fleet. — European sail mixed with Asian junks — an East Asian free port photographed in the last age of sail.
• era_marker: A sepia albumen print with soft tonal range, made from a large glass negative; the sky is blank from overexposure. — Albumen printing places this in the 1860s-70s, the first generation of commercial photography in Asia.
