The World is Going Upside Down: Grand Prize Winner and Gold, Animals in Their Habitat category. To make this image of a Bornean orangutan in Tanjung Puting National Park, the photographer climbed a tree and waited. “I selected a tree that was in the water so that I could get a good reflection of the sky which can make the image look upside down. Then I climbed up the tree and waited for hours. This is a regular path for the orangutans to cross to another small island so I was sure to get this frame if I waited patiently.” #
