Alexander Safonov is a software architect from Voronezh, Russia who currently lives and works in Discovery Bay, Hong Kong. Not content to sit in front of a computer full-time he obtained a diving license in 2002 and started to experiment with underwater photography about two years later. He has since made numerous excursions to photograph underwater wildlife off Cocos Island, Fiji, the Galapagos and Raja Ampat. However his favorite destination is the annual sardine run off the coast of South Africa where most of the photos you see were captured over the last few years. You can see much more of his work on Flickr and 500px.
