Mixing Electricity and Photography
As a lot of you know, I like my Photography so I was so happy to stumble upon this...
’’ A form of photography that uses electricity. It’s actually a type of photogram / contact print. i.e - photo taken without a camera by placing objects directly on light-sensitive paper and exposing them to light.
In this case the surface on which the object is placed is exposed to electricity.
Accidentally discovered by Russian inventor Semyon Davidovich Kirlian, thus the name.
Typically, Kirlian photography involves a metal plate with a sheet of film on top, and the object to be photographed placed on top of that. High voltage is momentarily applied to the plate, onto which the corona discharge is then copied.
A corona discharge occurs when a current flows from one electrode to another through a neutral fluid, like air, by ionizing that fluid. The ionization creates a region of plasma around the electrodes. The plasma goes around whatever object is placed on the plate, thus following its shape.
Pretty cool eh!!!
’Everything about Kirlian photography, at the very least, can be scientifically and rationally explained despite the spooks and freaks getting all mystical about it.
