John completed his wildlife biology degree in 1977, but then he decided to become a full-time nature and outdoor photographer and never looked back. He has led more than eighty international photo tours (including forty trips to Kenya and twenty to the Galapagos) and taught hundreds of field workshops and one-day seminars all over North America. His passion for photography is only matched by his zeal for teaching. He is a tremendously enthusiastic instructor and public speaker who is able to explain the most advanced photo concepts in easy to understand terms. A prolific author, he writes a column for Nature Photographer magazine. Focal Press has published five of his best-selling instructional nature photography books. His upcoming book on advanced outdoor flash techniques will be published in late 2016.
