1. Artist Luis Hernan has turned Wi-Fi signals into beautiful photographs, each in a different space.
2. The work, called “Spirit Photographs,” is part of a larger project called Digital Ethereal.
In capturing what Wi-Fi signals look like, Hernan believes society can see how it can influence the every day presence of technology in our lives. “Wi-Fi seemed the best option in exploring how wireless technologies affect and are affected by physical spaces and by human behavior,” said Hernan to BuzzFeed. “For me, it has a more direct relationship to the scale of, for instance, a house where most of daily life occurs.”
3. Hernan, a PhD candiate at England’s Newcastle University, captured the hertizan space of Wi-Fi signals on camera.
Hertizan space is the “electro-climate” of electronic devices. Electromagnetic signals can be observed and recorded to see how these devices interact with a space.
4. To photograph these images, Hernan used a Kirlian Device and long exposure rates.
The device can “detect nearby Wi-Fi signals then lights up a certain color based on strength of the signal,” The Daily Dot reports. Red indicates a stronger signal, whereas blues and greens denote a weaker one.
5. “Wireless technologies are generally taken for granted, to the point where they are regarded as banal infrastructure,” said Hernan.
Wi-Fi signals, which can be influenced by a number of variables, are seen here as varying in their strength.
6. “I believe that in encountering [wireless technologies], we generate narratives which change the way in which we see ourselves,” said Hernan.
7. Hernan’s work, “The Secret Body of Wireless,” was exhibited at the Newcastle University.
Along with the Spirit Photographs, visitors were able to see an Android app version of the Kirlian Device and could use Google Glass to access it as well.
