This image was made at an eruption from Sakurajima Volcano in southern Japan, Kagoshima province. Having waited for more than half a day it was necessary to catch this moment some seconds after the beginning of this eruption. Sakurajima is having zero to half-a-dozen eruptions per day, and only some of them causing lightning. This example documents the strongest lightning in a whole week.
In addition, it was my third travel to this volcano, and until now I never saw such a strong lightning. So this image is a result of extreme patience, optimized night photography, technique and luck. You have to prepare for permanent camera power, focus drifting, mirror flap damping, dew protection, volcanic ash protection, instant reaction after days of waiting time, framing on well predicted eruption position, perfectly matching exposure time depending on moon position, dawn development, lightning intensity and so on.
There are very few volcanoes on earth which produce repeatedly volcanic lightning, on other volcanoes you have it only once in many years during big scale eruptions. This two-second night image, made with a Canon 5D Mark II and 200mm f/1.8 lens has nearly no postprocessing, only some local contrast and brightness corrections. - Martin Rietze
Equipment and settings: Canon EOS 5D Mark II, Canon EF 200mm f/1.8L lens - Two-second exposure at f/1.8 - ISO 800
