“This Astronaut’s Photography Manual has been prepared by Hasselblad in close cooperation with the Training and Man-Machine Divisions at the Johnson Space Center of the National Aeronautics and Space Administration. As a guidebook for the NASA Photography Training Program, it not only describes the operation of the Hasselblad 500 EL/M cameras used on the U. S. Space Shuttle but is also a concise manual on photography to assist astronauts in creating the best possible space photographs.”
