Part 6/8:
Emphasizing the mechanical workings behind flash photography, high-speed filming techniques unveil the inner workings of flashbulbs and flashcubes. To better comprehend the flash processes, modern content creators have turned to slow-motion technologies to dissect the explosive initiation of flash.
The mechanics reveal that both electrically-triggered flashbulbs and flashcubes contain explosive compounds to initiate the burn of materials like zirconium. When the trigger is hit—either through electrical discharge or mechanical operation—a rapid chain reaction occurs.
