The annual fireworks competition in Helsinki was fired off Hernesaari this year. Two sudden rain showers interrupted the show, and security had placed the fence quite a long way away from the fire and explosions - otherwise the event was nice. Taking pictures of fireworks is fairly easy with the right equipment, these are shot with a 40mm lens stopped down to F10 and exposing by hand via cable-release in bulb-mode for whatever seemed to be a suitable time/display. Bring a tripod.
