Definition of Nature Photography

Nature photography, or natural photography, captures the beauty of natural elements found in the outdoors all within a frame. It typically includes wildlife, plants, and close-ups of natural scenes and textures.

Famous Landscape and Nature Photographers
Ansel Adams (1902-1984)

Ansel Adams, who was commissioned to capture the national parks with the most famous images being from Grand Teton National Park and Yosemite National Park.
He also wrote three books that are considered the bibles of photography—The Camera, The Negative, and The Print. These three very dense and technical books, including the Zone System, cover the entire photographic workflow.
Elliot Porter

Elliot Porter is known for his specialization of color photography and Ansel Adams described Porter as "master of nature's color,". Porter's contemplative intimate landscapes bear witness to his enduring affection and respect for the wilderness and its animal inhabitants. Influenced by Henry David Thoreau, Porter sought to create visual equivalents of passages from Thoreau that inspired him.
