Captured four upward lightning flashes to the towers in Rapid City, SD. The first flash was captured while driving to the observation location and video captured at 1,000 images per second is shown below.
Lightning is one of Nature's most spectacular displays. I document lightning with high-speed cameras and electromagnetic sensors to better understand this phenomenon. My current focus is on Upward Lightning which initiates from the tip of tall objects and propagates upward towards the clouds above.
