*** Deep Diving ***
Discover a world still unknown!
The vast majority of underwater photographers are content to explore areas close to the surface. In less than 30 meters deep for the most part. Some photographers go down from time to time up to 60 m, but they are already few. After 60 meters of depth, the number of divers completely collapses. Of these, the proportion of underwater photographer is tiny. Yes, we are very little to evolve and photograph at such depths. The small number of divers moving at these depths is mainly due to the commitment that this type of diving imposes. It is no longer a question of recreational diving but rather of technical diving, often called: Tek diving.
These dives involve a strong personal commitment, technical and financial. Above all, it will be an experienced diver to consider training on a closed circuit rebreather: The essential machine to descend to these depths. But this is not enough! After acquiring an indispensable experience with these machines in shallow depth, it will be necessary to pass a Trimix training! Once this Trimix training is acquired, the twilight zone becomes accessible. But not without consequences and without risks!
This type of diving involves the management of several gases. Some of these gases are hypoxic. it means that you can not breathe them on the surface, or close to the surface. Others are enriched with oxygen and have a breathable depth limit. Each gas is adapted to a depth range, which makes the dive complex. This type of diving involves a long training, practice and training. Each immersion requires precise planning with a decompression protocol adapted to diving. Decompression times are very long. A few minutes spent in the darkness of the depths you will be worth several hours of decompression with a rise to the surface at a controlled speed. During this lapse of time, the diver is vulnerable. It must not exceed the virtual ceiling or risk serious complications, not to say a fatal outcome. Deep diving is out of reach for everyone, deep diving photography is even less so.
Taken between 70 and 120 meters deep (and soon more), a large number of photographs of this gallery are unpublished. Being in contact with an international and multidisciplinary group of scientists and oceanographers, these photos are the subject of studies and each shot brings a little more information on this environment which is still very poorly known.
