New Zealand based photographer, David Wall, developed an interest in photography during travels overseas. These included several years' work as an expedition tour leader in Africa which resulted in the publication of his first book Visions of Africa. This has been followed with a further 13 publications. Since then David has also built up a large online collection of over 30,000 images of Australia and New Zealand (plus other international destinations such as the United Kingdom, Africa, Fiji, Chile and Canada). For over fourteen years he has been supplying images for every conceivable use, and supply clients around the world with high quality images for use on a range of products from books, brochures, websites, calendars, banners and posters, up to murals and billboards. Aerial photography is one of his specialties. David has conducted over a hundred aerial shoots throughout New Zealand and has a growing collection of Australian aerial photos.
