Luis Hernan is a student at Newcastle University who is pursuing a PhD in Architecture and Interaction Design. Hernan created what he calls a Kirlian device, an instrument that reads the signal strength of WiFi networks and translates the signals into five-color LEDs. Red indicates the strongest signals, blue represents the weaker.
Using his equipment, Hernan shot this long-exposure photo series, which he calls Spirit Photographs. Hernan explained his thought process:
"The fact we are becoming increasingly reliant on something that we can't see intrigues me. I wanted to find a way to show the wireless which is around us and also to show how it changes."
