Cian O'Brien, Limerick, letting it rip with some steel wool on top of an old ESB pump house on the river Shannon in Limerick. This is a long exposure night photo taken on my new GoPro HERO5 camera. I opened the shutter for 30 seconds to allow maximum light in to the sensors. I set the ISO limit to 100. This photo is not edited.
