Emory Kristof has been a National Geographic magazine photographer ever since he started working at the publication as an intern in 1963.  He is a specialist in scientific, high-tech and underwater subjects, including deep ocean work that places him far beyond normal diver depths. Throughout his career Kristof has been a pioneer in the use of submersibles and remotely operated vehicles.  He created the preliminary designs of the electronic camera system for the Argo, the underwater vehicle that aided in the discovery of the famed Titanic. He has documented many legendary shipwrecks, among them the Edmund Fitzgerald, the Hamilton & Scourge, the Breadalbane, the 16th Century Spanish Galleon San Diego, the interior of the USS Arizona, as well as the aforementioned Titanic.
