By his late teens in the early 1980’s David had begun selling pictures but still needed a day job. All that changed when in 1988 he made his first trip to East Africa and took a picture that would soon start making more money every month than he was getting from his salary. This is the story of how David made that leap from day job to pro wildlife photographer. He has witnessed first hand the rise and fall of stock photography, managed a picture library for a decade, been the author or commissioned photographer for nearly 50 books and led over 200 tours. This talk is about the business of wildlife photography and how David has done it. He will show some of his key images, some of which have sold many hundreds of times and will explain why they have had such wide appeal.
