Glass and Water
Underwater photography may conjure up the vision of a SCUBA diver weighed down with an apparatus that costs more than a decent used car. And something that requires a degree in physics in order to operate it.

In years gone by this would have been a fairly accurate assessment, but times have changed. Inexpensive and simple-to-operate cameras are available with waterproof casings, and many people may be wondering how best to use these without having to take up SCUBA diving.

Equally, many established underwater photographers will have come to the realisation that SCUBA diving is not always the best approach to obtaining certain images.

For both groups, it would be useful to have a definitive guide that describes how best to adapt to an aquatic environment for the purposes of photography, without the encumbrance of SCUBA equipment.

Glass and Water is this guide.

The book draws heavily on the techniques and equipment of competitive freedivers, who require the ability to be underwater for as long as possible to obtain their goals. Goals that are not dissimilar to those of the underwater photographer.

'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

'Mark Harris manages to marry the disciplines 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.' - Steve Weinman, DIVER Magazine
