Film drive motor and camera shutter are interlocked with electronic flash so camera can be operated blindly at depths up to 6 miles, with lash occurring only when shutter is open.. Adjustable mechanical time-delay switch S1 delays start of operating cycle until camera is at operating depth. Timing switch S2 then takes picture every 12 sec for two hours.-H. E. Edgerton and S. O. Raymond, Instrumentation for Exploring the Oceans, Electronics, 33:15, p 62-63.
