Photographer Luis Hernan uses long exposure photography to turn Wi-Fi signals into these fabulous multi-colored digital trails. The photographs in his project, ” Spirit Photographs – Wireless Spectre”, resemble new age ghosts floating through stairwells and open spaces. Hernan uses something called the Kirlian Device. This turns wireless signals into colors depending on the signal strength, blues for strong signals and reds for weak ones. The end results truly amaze!
