Tri-X is a classic high-speed black and white photographic film from Kodak. Introduced in 1954 at a rated speed of ASA 200/24° DIN, it was the first high-speed black and white film. Today it is available in two speeds, ISO 320/26° (320TXP) and 400/27° (400TX). Tri-X 400 is the more common of the two, coming in 24 and 36 exposure rolls of 35 mm and 120 as well as 50 and 100ft bulk rolls of 35mm. Tri-X 320 is available in 120 and 220, as well as 4×5", 5×7", and 8×10" sheets. Tri-X 400 is rated at ISO 400 when processed in standard developers and remains among the fastest black and white films today. Push processing Tri-X to EI 800 in a standard developer brings very good results, while further pushing to EI 1600 requires more sophisticated processing. Tri-x was once one of the most popular films used by photojournalists, but it declined in the 70's and 80's due to the falling price and increasing popularity of colour film. Since the advent of digital photography it has all but fallen out of use in newspaper journalism. Apart from possible use in educational establishments, it still remains reasonably popular in documentary journalism.

The National Geographic Society, headquartered in Washington, D.C. in the United States, is one of the world's largest not-for-profit educational and scientific organizations. Its interests include geography, archaeology and natural science, the promotion of environmental and historical conservation, and the study of world culture and history. Its historical mission is "to increase and diffuse geographic knowledge while promoting the conservation of the world's cultural, historical, and natural resources."[1] Its President and CEO since March 1998, John M. Fahey, Jr., says National Geographic's purpose is to inspire people to care about their planet. The Society is governed by a twenty-three member Board of Trustees composed of a group of distinguished educators, businesspeople, scientists, former governmental officials, and conservationists. The organization sponsors and funds scientific research and exploration. The Society publishes an official journal, National Geographic Magazine, and other magazines, books, school products, maps, other publications, web and film products in numerous languages and countries around the world. It also has an educational foundation that gives grants to education organizations and individuals to enhance geography education.[2] Its Committee for Research and Exploration has given grants for scientific research for most of the Society's history and has recently awarded its 9,000th grant for scientific research, conducted worldwide and often reported on by its media properties. Its various media properties reach about 360 million people around the world monthly.[3] National Geographic maintains a museum free for the public in its Washington, D.C. headquarters, and has helped to sponsor such popular traveling exhibits such as the "King Tut" exhibit featuring magnificent artifacts from the tomb of the young Egyptian Pharaoh, and currently touring in several American cities, presently in Philadelphia at the Franklin Institute.
