"Electric flows"

During the thunderstorm on the night of June 10, 2022, over central Evia isl., Greece, there were many CA (Cloud-to-Air) lightning. In one of them, it was possible to capture the corona discharge with its distinct blue/purple color. These purple filaments/streamers are created due to high values of the electric field (high enough to ionize air molecules, mostly nitrogen). In this image, I've done a "double zoom in" so one can easily observe this phenomenon. Sigma Art lens 20 mm (big frame), 85 mm (smaller frames), at f/1.4 and iso 20-40k.
