What is the principle of lightning photography?

1In September, 823, a sailor was killed by lightning, and the figure of horseshoe was clearly engraved on his thigh. The horseshoe was nailed to the mast, just above the sailor's head. A little boy climbed a tree to get the eggs from the bird's nest when the tree was struck by lightning. The little boy's chest is clearly branded with the image of the tree he climbed, as well as a bird staying on the branch and a nest next to it. 1892 July 19, two black people were killed by lightning in Pennsylvania, USA, when they were sheltering from the rain under a tree in the park. When people took off their clothes from kessel, they saw a shocking spectacle: the photo of the lightning location was left on the chest of the deceased, and a brown oak leaf and fern grass were hidden in the grass. The images of leaves and ferns are so clear that even the smallest tendons can be seen with the naked eye. 1976 One noon in summer, dark clouds were gathering and heavy rain was coming. Amos Pixar, a farmer in Michigan, USA, saw a group of black cats barking in the yard. He picked up a stick to disperse them. Just as Pixar held up a stick and cut at the cats, there was lightning and thunder, and the black cats all died tragically. At the same time, Pixar felt a sharp pain all over his body and cramps in his hands and feet. He staggered back to the house. The wife saw that trouser legs on his left leg and his long shoes had been torn by lightning from top to bottom. Looking at her husband's baldness, the wife couldn't help exclaiming and fainted. It turned out that a clear black cat image was printed on the bald head, which was lifelike and frightening. When Pixar's wife woke up, she immediately brought soap, detergent and brush to clean the image on her husband's head, but the image of the black cat could not be washed away, and it was firmly printed on her husband's bald head. The next day, the strange "black cat photo" on Pixar's head faded by itself, and it all disappeared at noon. 1957 a female ranch worker in the United States was working in a thunderstorm when suddenly a huge thunder sounded. Although she was not hacked to death, she felt chest pain. When I untied my coat, I found the image of a cow printed on my chest. In Russia, after a pedestrian was struck by lightning, all his clothes were gone, only the sleeves of a shirt and some nails on his boots were found. 10 minutes later, he regained consciousness and was very surprised to see himself naked. In Austria, a doctor came home from work and found his wallet stolen. His wallet is made of tortoise shell with two crossed "D" characters inlaid with stainless steel, which is the abbreviation of his name. That night, the doctor was asked to rescue a foreigner who was struck by lightning. The man was lying under the tree, dying. During the examination, the doctor suddenly found that the man's thigh skin was clearly printed with two words "D", which were exactly the same as his wallet. As a result, he found his wallet in the foreigner's clothes pocket. This "lightning photography" has happened many times in modern times. 1766 In a village in France, a man stood in front of a tree that had just been struck by lightning. He suddenly found the image of the tree on his chest. 1853 On August 26th, a similar phenomenon happened in America: a girl stood in front of a window with a small maple tree outside. After a flash of lightning, people found that the little girl was printed with the image of this small tree. Russia also found an image of a child with delicate branches and leaves printed on it during a thunderstorm. July 1984, 10 The suburb of Anshan, Liaoning Province 14 Wang Xiaomei, an 85-year-old woman who was blind, finally saw the light again after a burst of lightning and thunder. Similar examples have happened abroad. 1On June 4, 980, Robinson, an American who had been blind for nine years, took shelter from the rain under a big tree outside the house and was constantly struck by lightning, and he was unconscious. After waking up, he dragged his weak legs home to sleep. After waking up at night, he can see everything in the house. 1980, a blind old man in India saw the light again after a thunder. In You Ning, USA, after a lightning storm, a housewife opened the refrigerator and was surprised to find that the frozen raw chickens and ducks turned into cooked roast chicken and roast duck, and other vegetables and fruits also turned into cooked food. In the Hawaiian Islands, a group of people set up a barbecue grill in the wild with a little suckling pig on it. After a burst of thunder, the little suckling pig cooked without roasting. 1one day in the summer of 956, a strong lightning strike occurred in Kensington, USA. A minefield hit a livestock farm vertically and dug a deep hole with a diameter of 30 cm and a depth of 9 meters. This hole later became a drinking well for local residents. 1987 On June 919, five small experimental rockets will be launched from the launch site on Varops Island, Virginia, USA. Suddenly there was a burst of lightning, and three rockets were hit by lightning, which induced automatic ignition and then crashed. This has become another space accident that shocked the world after the explosion of the space shuttle 19861Challenger on October 28th. In order to explore the causes of lightning photography, according to the data, some people speculate that in an environment with strong magnetic field and under suitable temperature and humidity conditions, nature can store the images of people and animals through some unknown mechanism and release them again like a video recorder under the same conditions. The above examples show that lightning photography is a natural mystery that has not yet been deciphered. Its formation must be related to the high voltage discharge during lightning, the formation of atmospheric plasma, humidity and temperature. Whether there is still magnetic field involved and what is the storage medium need further discussion.
