I was previously selling signed copies of the book through this page. But I have stopped this service, currently. I may restart it later in the year when I am at home and free to sign copies and lug books to the Post Office!
Amazon USA is now shipping (from 28th July 2016). The book is also available widely in North America such as at Barnes & Noble and from specialist underwater photography retailers, such as Reef Photo & Video.
Digital iBook released December 2016. Contains 100 additional images and 50 short tutorial videos. Available in 51 countries from Apple iBooks store, search “Alex Mustard”.
Digital kindle edition released June 2017. Contains 100 additional images compared with print edition. Available from Amazon, search “Alex Mustard”.
I also hope that the book will be in stock at most specialist retailers (UW Photography Shops and Photography Focused Dive Resorts) widely soon. If you own one of these please contact me and I can put you in touch with the publisher, who holds the stock.
