Most cloud-to-ground lightning is "negative lightning," where the initial leaders are negatively charged. This spurs a return stroke with the reverse electrical charge to zip in the opposite direction. Lightning begins when a channel of electricity called a leader travels from one charged area to another - say, from a cloud to the ground, or from one layer within a cloud to another.

So I was somehow relieved my shutter had broken or I might have been in trouble.'Lenz used a Canon 5D mark1 camera and a Sigma 150-500 lens to capture the magnificent scene.'I set the camera on a tripod and aimed it towards the windmills where there was a high concentration of lightning strikes,' he said. I put my equipment away and got in my car and then realized the lightning had gotten dangerously close. 'This photo is the last one I got when my shutter broke. Lenz snapped this electrifying shot during a storm on July 20, 2012.'I was out in the middle of this storm with lightning crashing all around (a few miles away) and excitedly taking photos,' Lenz told LiveScience in an email. The region is characterized by rolling hills, and treeless agriculture, he said. Photographer Steve Lenz captured this incredible lightning photo in northeast Oregon, outside the city of Milton-Freewater.
