Accidental Thinking on killian's Photography

Xie Miao Davidovic killian is a clever and studious electrical technician in Armenian Soviet Union. He discovered the so-called "killian halo" at 1937. When repairing electrotherapy equipment, a spark discharge occurred between one of his hands and the electrode covered with glass on the equipment. This aroused his curiosity. He wants to explore whether the sparks around the palm of his hand will be recorded on photographic film. Killian burned himself in his first experiment, but he really took a picture of his hand surrounded by halo.
