"From birth, man carries the weight of gravity on his shoulders. He is bolted to earth. But man has only to sink beneath the surface and he is free."
- Jacques-Yves Cousteau (1910-1997)
In his childhood Tobias Friedrich loved to watch the adventures of the Calypso with Jacques-Yves Cousteau as its captain and the beauty of the world that is below the ocean's surface. It's still an overwhelming feeling for him when he has the chance to dive. He loves the elegancy and calmness of the world under water standing in contrast to the hectic atmosphere above.
Tobias Friedrich lives in Germany and started taking pictures with a DSLR underwater in the year 2007. Since then his images have been published in prestigious scuba diving magazines such as US Sport Diver, Unterwasser, Tauchen, Scuba Diver Through The Lens and many others. Several underwater photographic competitions, including Smithsonian’s Ocean Views, Ocean Art, Epson Red Sea, Beneath the Sea, and Celebrate the Sea also have honoured his work as well. He is always passionate for new challenges and up for new, creative ways in underwater photography. He is using a Canon EOS 5D Mark II in an SEACAM housing.
Dr Alexander MUSTARD, 41, from the UK, has been taking underwater photographs for 30 years and has worked as a full time underwater photographer for the last 10 years.
His photographs have attracted many awards including being category winners in both the Wildlife Photographer of the Year and British Wildlife Photography Awards. In 2013, he was named European Wildlife Photographer of the Year as overall winner of the GDT contest. The first time an underwater photograph has won this prestigious award.
In 2016 he published two books: Underwater Photography Masterclass, considered required reading by all underwater shooters and the critically acclaimed Secrets of the Seas in collaboration of Professor of Marine Conservation Callum Roberts. His previous book, Reefs Revealed, won the International Grand Prize for the best book of underwater photographs.
In 2015 he founded the Underwater Photographer of the Year competition, and has acted as a judge for the Wildlife Photographer of the Year, European Wildlife Photographer of the Year, the CMAS World Championship of Underwater Photography and most major underwater photography contests.
Alex is a regular contributor to many publications in the marine, wildlife, diving and photographic media, and to date has published more than 400 articles. In addition to various features, he currently writes two monthly columns on underwater photography: IMAGES Column for Sport Diver (USA) and Be The Champ for DIVER Magazine (UK).
He was one of team for the 2020VISION conservation photography project in the UK. He also runs highly popular underwater photography workshops at top diving destinations around the world.
Jeffrey Bozanic is an extremely active technical diver and instructor. Specializing in rebreather use, he is probably best known for his seminal textbook on the topic, Mastering Rebreathers (Best Publishing Co.).
Jeff holds an MBA in International Marketing, a Ph.D. in Education, and spent another three years in Ph.D. level studies in marine geochemistry.
Jeff has worked for over 20 years as a management consultant, both within and outside the dive industry. He has also performed services as an accident investigator and expert witness, consulting on cases related to scuba fatalities and non-fatal dive related incidents.
Jeff’s scientific diving began in 1978, when he was working on his thesis for his degree in geology. He spent a year dredging for gold, analyzing the settling velocity of natural alluvial gold particles. He later studied the effects of water chemistry in underwater cave systems, and has collected many new animal species from submerged caves. In addition to his research, he has overseen scientific diving programs in Antarctica as part of the U.S. Antarctic Program, the University of Southern California as Diving Safety Officer, and on multiple diving control boards of various academic diving programs.
Jeff started teaching technical diving in 1983, long before the term “technical diving” was coined. Originally specializing in cave and decompression diving instruction, he later branched out into teaching nitrox and trimix. He currently conducts rebreather, cave, nitrox, advanced nitrox, decompression procedures, and trimix diving courses, as well as instructor courses.
He has published extensively on diving education topics, with heavy emphasis on cave and rebreather diving. He has edited/reviewed many diving textbooks, including co-authoring the Antarctic Scientific Diving Manual and editing The NOAA Diving Manual.
Jeff served on the Board of Directors of NAUI, NSS Cave Diving Section Board, IANTD Board of Advisors, and the TDI Rebreather Advisory Board.
His contributions to diving safety have been recognized with many awards, including the Platinum Pro 5000, Silver Wakulla, International Safe Cave Diving, NAUI Hall of Honor, TDI Professional of the Year, the 2007 DAN / Rolex Diver of the Year, and in 2014 received NAUI's Lifetime Achievement Award. His contributions to underwater sciences were recognized by the American Academy of Underwater Sciences' Conrad Limbaugh Award for Scientific Diving Leadership in 2015.
