HONG KONG — Michael Wolf, a photographer who was known for his vertiginous depictions of rainbow-hued skyscrapers in Hong Kong as well as the minutiae of everyday life there, died on Thursday at his home in Cheung Chau, an outlying island near the city. He was 64.

His death was confirmed by his longtime representative, Sarah Greene, and his studio manager, Pierfrancesco Celada. They did not specify a cause but said he had died in his sleep.

In photographs he likened to “supermarket bar codes,” Mr. Wolf captured Hong Kong’s high-rises — dizzying stretches of pink, green and orange — in a 2005 series titled “Architecture of Density.”
