This is a realistic landscape photography work taken in Quinault Rainforest, Olympic National Park, Washington, USA. As a world-famous temperate rainforest with humid climate all year round, its tall tree trunks are covered with thick bright green moss, and the ground is covered with layers of wild sword ferns. Faint sunlight filters through forest gaps, the whole forest is full of primitive natural vitality, quiet and deep, full of fresh moist natural atmosphere, which is a representative North American temperate rainforest landscape.
