Lightning Shots?

I was randomly thinking about shooting during storms, mainly for lightning and came up with a question that I bet has been asked before:

How do the pros take shots of lightning bolts? Do they use some kind of motion detectors that react that quickly?

I assume it's no where near my range of skill or gear, but I was just wondering.

small aperature loong shutter times.. sonetimes from 1-30 even more mins

Ohh wow very cool, I figured it was a matter of speed shooting, leaving the shutter open for that long makes sense too though.

Thanks!
