Single Shot #28
After the last post, #27 Rainy Night, I decided to post another weather related image. This time it is a lightning bolt. I tried shooting lightnings many times and almost all the images that I captured were not that great. I would rate this image as probably mediocre, but it will serve as a record of an early attempt.
It is difficult to capture lightnings because one, you need to wait for a thunderstorm and two, you need to be quick. The technique I used was to keep the shutter open and cover the lens with a black cardboard. I will uncover the lens momentarily a few times while the shutter is open. By doing so, there is a higher probability of capturing one or more lightning strikes.
It took many tries before I managed to get a few shots, while hoping that the storm will continue for a little longer.Some colour correction was done to the image.
The temperature of the air that is heated by the lightning bolt is around 25,000° C. This is 3 times hotter than the surface of our sun.
The lightning has an electric potential of 100 million volts. An average lightning strike discharges 20,000 to 30,000 amps and the estimated peak power of of each lightning bolt is 1,000 Gigawatts.
