This book focuses on the practical art of taking underwater pictures through the author's popular 'think and consider' system. Practical examples take you step-by-step through the basic techniques, from photographing shipwrecks, divers, fish and abstract images to taking photographs at night and 'dual lighting.'Written in a clear, non-technical style and illustrated in color throughout, this book has established itself as the introductory guide to photographing the wonders of the underwater world. It has now been fully updated and expanded to include five new chapters containing new techniques and examples, more inspirational images and the very latest equipment.
