Thunder rumbles ominously in the distance. The forest floor is soaked and muddy, with small streams forming from the heavy downpour. Branches sway violently in the storm wind. Shot with a fixed, wide-angle camera position that captures the full scope of the tempest, dramatic chiaroscuro lighting from lightning strikes, deep shadows contrasted with intense white light, cinematic composition with rich blacks and stark highlights, moody atmosphere of nature's raw power and fury."
