Diagnosed with autism at 3, Stephen Wiltshire quickly became fascinated with drawing London buildings, and by age 8 he was sketching Salisbury Cathedral for former Prime Minister Edward Heath. Known as “the living camera,” he can draw an accurate, detailed picture of a subject after seeing it once — including subjects as complex as major cities. He’s completed enormous canvases of Tokyo, Rome, Hong Kong, Frankfurt, Madrid, Dubai, Jerusalem, and London, drawing each from memory after a helicopter ride.

Below is the full time-lapse of his portrait of Singapore, drawn from memory over five days in 2014. “That he has a gift makes no sense at all to Stephen,” his sister Annette told the New York Times. “He knows that he draws very well, but he picks that up from other people — he sees the warmth on their faces, they tell him how much they like his work, and that makes him very happy. He loves the attention.”
