SUMMARY
Several key technologies in modern photography and videography originated from military development. The zoom ring on contemporary lenses can be traced back to a viewfinder accessory used by the US Army Signal Corps on combat movie cameras during WWII. Color infrared film, initially developed as a camouflage detection tool, was crucial for distinguishing vegetation from artificial cover. Additionally, night vision technology, starting with active infrared devices like the Sniperscope, was pioneered by the military for combat operations.
TAKEAWAYS
Zoom lens technology evolved from military viewfinder accessories used on combat cameras.
Color infrared film was developed by the military for camouflage detection, rendering vegetation red.
