This is a classic landscape photography work taken at Iguazu Falls, a world natural heritage site on the border of Brazil and Argentina in South America, one of the largest waterfall groups in the world. Layers of waterfalls rush down from cliffs covered with dense tropical rainforest. The aroused water mist refracts a clear rainbow across the river under sunlight. The foreground is a viewing cliff covered with bright green grass, under the clear blue sky. The surging river rolls with white waves at the valley bottom, fully showing the magnificent beauty of nature.
