From 500 feet above Victoria Harbour in a Cessna 172, or from swaying bamboo scaffolding, Cliff Wallace recorded in photographic detail the development of Hong Kong's newest landmark. From the first planning meetings and the start of the land reclamation, through to the last piece of the silver roof being bolted into place, Mr Wallace took more than 10,000 pictures. 'The unique characteristics of the construction, the architecture and the people involved were all worthy of recording,' he said. 'This project was a photographer's dream. There were thousands of elements to focus on: people climbing bamboo; silhouettes through the support structures; the shapes formed by the steel; and the curves of the roof.' A memorable moment was when the QE2 was moored opposite the convention centre providing an historic background for pictures taken from the roof. Mr Wallace often flew a Cessna light aircraft from Sek Kong. 'As you come through the harbour at an altitude of 500 feet . . . it's almost like one of those Omnimax movies. Between Green Island and Hong Kong Island, you suddenly come upon the magnificence of Hong Kong harbour and you get a wonderful perspective. 'It's almost as if Kowloon disappears because looming there are the two magnificently tall structures: the Bank of China and Central Plaza and they are complemented by the extension's sculpted roof and low elevation.' The dramatic change in the Hong Kong skyline provided a challenge to do something unique. The photographs of the extension from the air confirm the challenge has been met.
