This photograph of an oak tree was taken in 1948, in Yosemite National Park, by the late Ansel Adams (1902-1984). It was originally a gelatin silver print. The gelatin silver process was introduced at the end of the nineteenth century. The paper, or film, is coated with gelatin and silver salts. It was used for black and white photographs such as this one.

Oak Tree, Snow Storm was one of many photographs by Ansel Adams that was taken in Yosemite National Park in California. His black and white photographs from this area are what he is particularly known for.

Adams was a pioneer of photography, being one of the first photographers to have his work displayed in a gallery alongside paintings. Along with Fred Archer, he developed the Zone System. This is a technique that determines optimal film exposure.

It is this technique that gives his photographs their signature depth and clarity. He preferred the use of large format cameras because the high resolution also helped to ensure sharpness in his images. He also founded a group that brought together photographers who used similar techniques.

This is not his only 'Oak Tree' photograph - other examples on this website include 'Oak Tree, Sunrise' and 'Oak Tree, Sunset City, California'. There are also many examples of his other work in Yosemite National Park.

Ansel Adams taught his craft to thousands of amateur photographers through workshops and publications. He wrote multiple books about photography, some of which have become classics in the field.
