The major tasks on AEC events were to photcgrepn
fireball growth for determination of yield and to record
cloud growth and motion.
DOD pro‘ects involved photography
of phenomena resulting from underwater and high-altitude
detonations.
Specific EG&G photogrechic commitments,
in-
cluding those for Operation Newsreel at Johnston Island, are
listed by project number in Table 3

Instrumentation.
For the laboratory shots, cameras were located at stations
on Bikini and Eniwetok Atolls.
These stations are listed in
Table 4.
To provide views of the fireball and of cloud formation
from different angles, at least two photo stations were used
on the smaller AEC shots and as many as four on the larger
shots.
Because of the complexities of the shot schedule,
EG&G had to be prepared to photograph either of two detonations at both Eniwetok and Bikini Atolis;
therefore,
each of
the six photo towers contained two complete sets of cameras
and control equipment.
