The Australian Institute of Professional Photography is an industry organization concerned with raising the standards of professional photography in Australia. Each year the AIPP holds the industry’s print awards called the Australian Professional Photography Awards, or APPA. During a four-day period, usually in May, nearly 2500 photographic prints, in various categories, are judged and scored by senior members of the institute. Amongst these awards is a category concerned with the publishing of photographic excellence in books the AIPP Photography Book of the Year Award. In 2008 this was awarded to Peter Adams book ‘Who Shot That?’.
