Emory Kristof is a specialist in scientific, high-tech, and underwater subjects, including deep-ocean work beyond normal diver depths. A pioneer in the use of submersibles and remotely operated vehicles (ROVs), he created the preliminary designs for the electronic camera system for the ROV that first photographed the rediscovered wreck of the Titanic.

Kristof has documented many other historic and challenging wrecks, among them the Edmund Fitzgerald, the 16th-century Spanish galleon San Diego, and the interior of the U.S.S. Arizona. In over four decades with National Geographic he has published over 50 stories, many of them cover stories.

Kristof was on the 1977 expedition that discovered deep hot-water volcanic vents and the unusual life-forms they sustain, off the Galápagos Rift. Recently he supervised the giant-screen film Volcanoes of the Deep Sea. Naming him a "Digital Innovator," Kodak described Kristof as "one of four great visionaries who have taken photography to the digital frontier and beyond."

Volcanoes of the Deep Sea: The Giant-Screen Film and Beyond
Journey with Kristof 12,000 feet (3,700 meters) below the surface, off the coast of Spain, to explore the hydrothermal vents and the unique creatures and environments they sustain.

Adventures With Sea Monsters and Robots
As the world's leading deep-sea photographer, Kristof has had the opportunity to track and photograph creatures that could star in sci-fi films—from sixgill sharks to giant squid to mysterious hexagon-shaped creatures. Experience the science and mystery of the deep.

Requiem for the Titanic
Kristof shares the development process for the Argo camera system and the expedition that led to the Titanic, lying peacefully on the floor of the Atlantic.
