I have been taking photographs since 1985. I have a photo library of over 12,000 entires, distributed among about 380 categories. I have published 29 books and articles on many of these topics, and routinely show them in galleries and photo competitions. In this book I use a different approach to display these categories, by showing only one photograph for 20 categories, which I hope will entice the viewer to see more on the same topic by contacting me
