In 1943, Ansel Adams (with camera) was granted access to the Manzanar Japanese-American internment camp to document the people held there. While Adams was not quite as a great a portrait or documentary photographer as he was at capturing the American landscape, he gave his subjects rich humanity and life.
He subsequently donated both his original negatives as well as some prints to the Library of Congress, without restriction. You can see them at

This is, of course, an oversimplification. Lange was an obvious master of formal composition as well as the technical craft of photography, and Adams, who served for decades on the board of the Sierra Club, fully understood the power of photography to influence public and political opinion. But the two approached their artistic practice from very different perspectives.
