For his work, photographer Don Naumann stands in the middle of a thunderstorm under a golfer's umbrella, camera at the ready, waiting for the next lightning strike. Don averages 1 to 2 quality photographs each year - and he's been doing this since 1991!
This one above is called "Mostly Scattered Showers," taken in Florida.
