Photography underwater has been a very interesting and rewarding experience for researchers and sports divers alike. Traditionally man has been intrigued by what he saw underwater and has wanted to show others the different and unique features of the underwater world. This paper explores innerspace photography and its usefulness not only to demonstrate you've been there, but also for research studies in the deep oceans relating to mineral exploration, deep sea ocean currents and sea mount studies. Platforms for suspending operational cameras and types of film are discussed. Usefulness of 70mm film type for enlargement and detailing are explored. Results of many different types of operational picture taking are presented and many examples of deep-sea photographs are shown.
