Description
This camera, invented by Dr Lucien G Bull in 1903, takes stereoscopic pictures at rates up to 2000 per second and was the first machine to analyse the wing-beats of insects succesfully. Dr Bull imprisoned the insect in a glas tube so that, when it flew out, it lifted up a tiny flap at the exit. This automatically closed the electrical circuit operating the camera shutter. In effect the insect was photographing itself.
