It also seems likely that the offset we observe fluctuates, and thus is not best compensated for via a static, systematic, adjustment. This potentially complicates the previously proposed Egyptian offset

3.1 GENERAL APPROACH
The general photographic approach leaned heavily upon the lessons learned from and equipment used for previous Operations In Nevada, The principal hazards to effects photography are blast, nuclear radiation, and obscuration by dust at shock arrival. Camera stations must be solidly constructed to avoid loss of the camera and record and to prevent undesirable motion of the camera Itself, The film must be shielded to reduce film fogging due to nuclear radiations. These two things can be done. It may not be a simple matter, but rugged well-shielded camera Installations are certainly technically possible though economically formidable.

The problem of dust obscuration is the most difficult one to cope with effectively. A vast quantity of dirt, raised from the desert floor and carried along by the shock front, obscures the picture at the precise moment when the record is most critical. The general solution to this problem is to elevate the camera above the dust. This procedure, however, further complicates the problems of blast and radiation protection. The higher the camera tower, the more rugged and expensive its construction must be. In addition, the problems of handling heavy radiation shields at substantial heights are manifold.

3.2 EXTERNAL PHOTOGRAPHY
In order to get above the dust raised by the shockwave, all cameras were placed on towers. These were the same towers used for the Military Effects Program on Operation Upshot-Knothole and were graciously loaned to the project by AFSWP. A typical tower is shown schematically in Figure 3.1, The tower consists of a guyed monopole with a small camera platform on top. The pole is an 8-inch steel pipe and is set in a reinforced concrete base, A cavity in the base houses the electrical control circuitry and batteriesc Both 18 and 10-foot towers were used by the project. The choice depended upon the height of the object being photographed and Its distance from ground zero.

Because of the requirements for shielding. It was advisable to use physically small cameras. Consequently, the 16 mm GSAP (Gun Sight Aiming Point) camera was chosen for all stations. This camera operates at frame rates of either 16, 32, or 64 frames/sec. The lead shield for this small camera weighs approximately 350 pounds.

In order to minimize the problems of dust obscuration. It Is necessary to place the camera tower as close as possible to the station being photographed. This Is accomplished by using wide angle lenses whenever feasible.
