Opis
English: Publicity photo of Croat-Serbian-American inventor Nikola Tesla in December 1899 supposedly sitting in his laboratory in Colorado Springs next to his magnifying transmitter high voltage generator while the machine produced huge bolts of electricity.

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. In his Colorado Springs Notes Tesla admitted the photo was a double exposure:

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!

and this is confirmed by Tesla biographers Carl Willis and Marc Seifer.

In 1899-1900 Tesla built the laboratory and researched wireless electric power transmission there. The "magnifying transmitter", one of the largest Tesla coils ever built, with an input power of 150 kW generated voltages on the order of 12 million volts at frequencies around 150 kHz, producing 140 ft. (41 m) "lightning" bolts.
Tesla sent a copy of this photograph to Sir William Crookes in England in 1901.

They now claim copyright. Note that the version in that archive includes a hand written note added in 1901 printing which doesn't appear on the more widely available image.

The unretouched image, without Tesla, appears in Nikola Tesla, "The Problem of Increasing Human Energy", Century Magazine, The Century Co., New York, June 1900, fig. 8
