Portrait of Hong Kong - Ho's final book project - shows old Hong Kong streets, quaint corners and harbour views photographed in the 1950s and '60s. The images in the book have a more natural, almost documentary style, and are very different to the highly stylised street photography that lovers of Ho's work are familiar with. The book has a foreword by film director John Woo and includes an essay by academic Joseph Fung and biographical notes compiled by Sarah Greene, director of Blue Lotus Gallery in Chai Wan.
