Yellow Stone Falls(1942c) is one of a series of spectacular photographs taken by famed photographer and environmentalist, Ansel Adams.

The photograph is a part of his National Parks project, commissioned by the US National Park Service.

The project includes striking photographs of several western National Parks during their formation.

The photos were taken during 1933-1942 and compiled in 1941-1942.

The series includes the famed Moon and Half Dome, Yosemite National Park (1942) and Tetons and the Snake River, Grand Teton National Park (1942).

The black and white photographs are characteristic of Adams’ style, using pre-visualization and zoning techniques; applying expert knowledge of saturation and exposure.

For Yellow Stone, Adams’ used selenium toning to preserve and produce darker tones, combined with a longer development time to increase the contrast in the final product.
