Stunning photos of rare, violent electrical storm

Folks in Christchurch, New Zealand, must still be talking about this weeks spectacular electrical storm, described by one meteorologist as a once-in-10-years event, producing severe hailstorms and hundreds of lightening strikes that set the twilight aglow. It was a dream night for weather photographers and Aaron Campbell made the most of the event, capturing a series of stunning images that look almost unreal.
