Dr Alexander Mustard has been taking underwater photographs since he was 9 years old and has worked full time as an underwater photographer since 2004. His photographs have won many awards, including regular success in Wildlife Photographer of the Year. His book publications include The Art Of Diving, which has been described by David Doubilet as “the best book about diving since Jacques Cousteau’s The Silent World”, and Reefs Revealed, which won the International Grand Prize for the best book of underwater photographs. His photographs have been displayed in exhibitions around the world and a particular highlight was presenting his work to Queen Elizabeth II. In 2013, Alex was named GDT European Wildlife Photographer of the Year for his image Night Moves - the first time an underwater photograph has won this prestigious award. Alex is a regular contributor to many publications in the marine, wildlife, diving and photographic media, and to date has published more than 500 articles. Alex was awarded the MBE in the Queen's Birthday Honours 2018 for services to underwater photography.
