Ever thought about all those invisible WiFi signals that must surround us all the time? Thought not. Well Luis Hernan obviously has. He has created a series of photographs showing the presence of wireless signals. The ghostlike images were created from a custom-build device that translates WiFi signal strength into colours and then uses a long-exposure on the camera to create these fascinating but eerie images.

PhD student Luis says “I believe our interaction with this landscape of electromagnetic signals, described by Antony Dunne as Hertzian Space, can be characterised in the same terms as that with ghosts and spectra. They are both paradoxical entities, whose untypical substance allows them to be an invisible presence”. These photographs are somewhat haunting in the same sense, they reflect a presence that is there and only captured by the camera not visible to the naked eye.
