Cave glow worms | Planet Earth

Developed by Japanese TV company NHK, the image intensifier (II) system has a camera chip 300 times more powerful than the standard digibeta camera used for most wildlife filming. It took only LED headtorches to light the cave sufficiently to see the 'gloworms'. Previously, they'd been filmed using time-lapse which creates a flashing effect that doesn't actually occur.
