We asked our contributors what their favorite images were, captured using ambient light only, and they came back with a diverse selection of photos featuring sublime underwater scenes from a variety of dives on reefs and wrecks, in caverns and cenotes, as well as with interactions with marine life. Here, X-Ray Mag contributors share their favorite images from the tropical waters of French Polynesia, Micronesia, Papua New Guinea, the Philippines, the Egyptian Red Sea, Mozambique, Bonaire, the Bahamas, Mexico and the Galapagos Islands, to the temperate waters of South Africa, Newfoundland in Canada, the US East Coast and California.
