Glass and Water: The Essential Guide to Freediving for Underwater Photography



In stock


Glass and Water is the first book on underwater photography for freedivers. With contributions from expert underwater photographers this book teaches the skills, knowledge and equipment necessary to successfully pursue underwater photography without scuba gear.

Rather than seeking to replace books on underwater photography, Glass and Water focuses on freediving techniques, equipment and photo opportunities. By carefully choosing or adapting freediving and photographic equipment some early hurdles can be avoided. Using appropriate freediving techniques can increase the length of time available for taking photographs underwater. And by being aware of the possibilities, frustrations can be avoided and good subjects sought out.

Includes photos and/or contributions from Fred Buyle, Sue Flood, Danny Kessler, Dr Anne-Marie Kitchen-Wheeler, Laura Storm, Andrew Sutton, Shane Wasik, and a Foreword by Dan Bolt.

Contents include: Foreword by Dan Bolt; Free­diving Equipment for Underwater Photo­graphy; Photographic Equipment; Underwater Photography Basics; Challenges and Opportunities for Freedivers; Lungcraft; Finning; Descents and Ascents; Neutral Buoyancy; Hydrodynamics; Safety; Creature by Creature; A Virtual Dive; Behind the Lens. Plus a Glossary of key terms.


‘It is clear that Glass and Water is a well thought through book that has been years in the development and writing. Mark has an encyclopedic knowledge of his subject and a clear and easy way of imparting his experience. The book is well laid out and designed and should be a must for anyone wanting to take pictures underwater’: gofreediving.co.uk

‘This book is required reading for those wanting to dive on one breath with a camera in hand… a great addition to a freediving course, and it will highlight what to improve on if you’re already a recreational freediver… Glass and Water helps you skip the pain points and shows you ways to be an efficient freediver-photographer from the get-go. This book is like having a talented and very British instructor whisper all his best tips into your ear. Mark knows what mistakes freedivers are prone to making and spells out exactly how to avoid them’: thesaltsirens.com

‘An outstanding resource for both novice and advanced freedivers, snorkelers and underwater photographers in general’: deeperblue.com

‘You will end up with an extensive skill set if you pursue all avenues of advice… A great addition to the bookshelf for photographers and freedivers’: learn2freedive.com

‘A very informative book which will help freedivers improve their images… The nicest surprise for me was the “Virtual Dive” chapter. This chapter alone was worth the price of the book… Glass and Water is obviously aimed at freedivers but scuba divers would also benefit from the content of this book’: UWP magazine

‘Mark Harris manages to marry the disciplines [freediving and u/w photography] without getting any more technical than necessary. He explains tricky concepts very clearly and, because no-one else seems to have tried it before, deserves credit for producing such a well-written and professionally produced book, generously illustrated with his and other freedivers’ photos’: Diver

‘It’s most unlikely that you’ll come away without learning something brand new and innovative… I’m very impressed indeed’: Martin Edge. (Read Martin’s full review of Glass and Water here)

‘Glass and Water should be as essential as a pair of fins and a camera for underwater photographers. Mark shares his tremendous expertise … the methodical and well-illustrated techniques will benefit anyone wishing to produce great images in the sea’: Brian Skerry
