Alexander Safonov is not quite your regular software architect from Voronezh, Russia.
Fascinated by the wet world that covers most of our planet, he trained and got his diving license in 2002 and started to experiment with underwater photography.
Since then, he’s made several trips to photograph the spectacular underwater wildlife off Cocos Island, Fiji, the Galapagos and Raja Ampat.
He has become especially taken with the annual sardine run off the coast of South Africa where most of the photos here were captured over the last few years. You can see many more photographs on his Flickr and 500px pages
