This impressive network of falls looks fine during the day, but in the dark with long exposures it gives it a much softer feel. I had to sneak back into the park at night, climbing through a cave on the way, to get this shot. Though it may not look it, the myriad falls produced an impressive din. I am used to near-silence when shooting nightscapes, so it was quite disconcerting as I wouldn't have been able to hear anyone, or an animal, approaching. These artful wooden walkways snake their way through several miles of trail, and past hundreds of waterfalls, at Plitvice National Park in Croatia.
