Ghostly Images of WiFi Signals Captured Using Long Exposure Photography and an Android App
So much of the world today is invisible to cameras. Technology operates in a light-less world of zeroes and ones, electromagnetic waves that fly over our heads in ever-increasing abundance.
For his fascinating project Digital Ethereal, designer Luis Hernan set out to capture one of these invisible signals, WiFi, using a creative combination of long exposure photography and an Android app.
Since you can’t just set up your camera next to your router, click the shutter button and capture a ‘stream’ of information pouring out, Hernan decided to ‘translate’ that info into light and color using an Android app called Kirlian Device mobile that visualizes WiFi signal strength using a series of colors.
