There is a company selling a "lightining trigger" for cameras. Best as
I've been able to ascertain, it is a couple flash-slave sensors tied to an
amplification circuit which then completes a circuit closure...
The lightining trigger is designed to trigger the camera's shutter upon the
flash of lightining. They recommend a shutter speed of around 1/2 second
with appropriate lens opening for the scene.
It seems to me that this approach would be much too slow to be of any
use, unless there are multiple strikes. I don't have the numbers
handy, but I seem to recall lightning is a millisecond phenomena,
whereas it will take a horizontal cloth shutter 18 mS just to open.
Or do I remember wrong?
