Episode No. 555 features artist Robert Adams.

The National Gallery of Art, Washington, is presenting "American Silence: The Photographs of Robert Adams" through October 2. The exhibition, a career survey, includes about 175 pictures Adams made between 1965 and 2015. It is accompanied by a catalogue published by the NGA and Aperture. Indiebound and Amazon offer it for $44-65.

Adams is among the world's greatest living photographers. His work has taken a critical eye to the United States, and especially to its stewardship of the West and the people who live there.

This is Adams' third visit to the program. He was previously the guest on Episodes No. 41 and 227.
