"For those not aware, to take a photograph of lightning you must open the
shutter and hope - or perhaps pray. You can't
wait until you see a flash and press the shutter release, as you will, of
course, have missed the event.
The trick is to frame the shot and set the camera for a long exposure, then any
bolts that appear in the frame will be
captured in all their glory. "
I've used this method, and although tedious and highly reliant on luck, it can
work. It's not the best way to assure
lightning images. The old way to do a better job is a flash trigger that senses
the pre-flash and triggers the camera.
If I were serious about capturing lightning nowadays, I would use CHDK on a
Canon to combine sensing and exposure in one
device. <http://chdk.wikia.com/wiki/Samples:_Lightning_photography>
