Lovely Underwater Photography ‘Experiments’ by Russian photographer Alexander Semenov, Chief of the diving team at the White Sea Biological Station (WSBS).
Much of his site, Clione 1.0, is unfinished, or is in the process of being translated from Russian to English but the photos speak for themselves.
He uses several cameras, both conventional (for in-lab images) and specialized underwater equipment (underwater housings).
His work is uniformly visually interesting. Have a look.
