Publicity photo created by using double exposure.

Publicity photo of Nikola Tesla sitting in his laboratory in Colorado Springs in December 1899. Photo was taken by Dickenson V. Alley, photographer at the Century Magazines. The laboratory was built in 1899. Tesla sent a copy of this photograph to Sir William Crookes in England in 1901. This image was created using “trick photography” via a double exposure. The electrical bolts were photographed in a darkened room. The photographic plate was exposed a second time with the equipment off and Tesla sitting in the chair. Tesla’s Colorado Springs notes identify the photo as a double exposure. (Source)

To give an idea of the magnitude of the discharge the experimenter is sitting slightly behind the “extra coil”. I did not like this idea but some people find such photographs interesting. Of course, the discharge was not playing when the experimenter was photographed, as might be imagined!
