Enlightening photography from Luis Hernan. Below is a description of the project from the artist’s website.
The series Spirit photographs—Wireless spectre is a performative and photographic exploration of Hertzian Space.
The pictures result from describing the space through a performance with the Kirlian Device, which transforms signal strength in light colour (reds for high intensity, blues for low intensity).
Coupled with long exposure photography, it is possible to register the changing qualities of wireless networks.
