Shane Tuck, a United States Navy mass communication specialist, conducting underwater photography training off the coast of Guantanamo Bay, Cuba, in 2012. Underwater photography is usually done while scuba diving, but can also be done while diving on surface supply, snorkeling, swimming, from a submersible or remotely operated underwater vehicle, or from automated cameras lowered from the surface. It frequently requires specialized equipment and techniques.Photograph: Jayme Pastoric/US Navy
