SUPPORT PHOTOGRAPHY The mission of Program 9 was to provide documentary and technical .. graphic support to participeting DOD agencies. > The documentary support c-~.. sisted of both still and motion picture coverage of project activities to depict the scope of the project's effort, and to show significant results of their effort, for historical and report purposes, Still photography, in support of projects for illustrating preliminary and final reports, was con- ducted by TG 7.1, TU-l. Notion picture coverage to be used in the production of a ‘\leapons Effects Film was provided by JIF=7. Technical photography,. such as high-speed, time-lapse, and function-of~time photography, was furnish- ed by TU-5 (2086), . During the planning phase of Operation HARDTACK, it became evident that the needs of the various projects for photographically collected data would fall on the five military effects events; two high altitude rocket detonations, one high altitude balloon detonetion, and two underwater detonations. Because of the veried nature and location of the detonations, more extensive and sophisticated camera installations were needed than on any prior opera= tion, For the high altitude balloon detonation, RB-36's were used with a beckup camera installation mounted on the USS Boxer. The photographic equipment used for all three high altitude detonetions consisted of streak, high and medium speed motion picture, rapid sequence still, and Zenith cameras, The photographic instrumentation for the two underwater shots was basi-- cally the same for each shet.
