Development came to Macau relatively late and the city is therefore reasonably well-preserved by East Asian standards. But much, inevitably, has nevertheless been lost, as any perusal of old photographs immediately indicates. I spent a year collecting old photos and then tried to match them to present-day Macau. The concept, one supposes, may not be entirely unique. The black and white past floats ghostily in the full-colored present, a sort of historical augmented reality made concrete.
