Remember, you do not have to be struck directly by lightning to be killed or seriously injured. Fatal voltages can be created in the ground as the current and energy flow away from and toward the strike point. You are at greatest risk of electrocution when your feet happen to be oriented along an imaginary radial line that extends from the strike point. The farther apart your feet, the higher the voltage potential between them as a result of a lightning strike. An intense voltage gradient exists around the strike point, with the highest voltages existing near the strike point.
Lightning also creates other risks.
A close strike can produce temporary blindness, similar to a flash bulb, but much more intense, especially at night. And, the thunder can be deafening and could cause permanent hearing loss. A direct or very close strike can kill you. Lightning photography is a dangerous and unpredictable activity. Enjoy the images, but understand the risks if you decide to photograph lightning yourself.
