The photo composite above shows the approach of a dramatic thunderstorm storm in rural Missouri, near the town of Forsyth, taken over a 15-minute span on August 6, 2011. It serves as a good example of why it's best to stay indoors during electrical storms. Note that not just the tallest or highest objects were struck by lightning; wicked cloud-to-ground bolts blasted tall trees, small trees, hill tops, and depressions with seemingly no prejustice.

Photo details: Canon EOS 7D camera; Canon EF50mm lens ; f/1.2L USM; f/9.0; ISO 320. Each exposure averaged 15 seconds, shot in "bulb" setting.
