Photographer Ansel Adams’ black-and-white landscapes conveyed an enduring appreciation for the natural world, and clearly, his work has influenced protegee Mariana Cook. While her 2005 book “Faces of Science: Portraits” didn’t contain breathtaking views of Yosemite, its portraits lionized those who study the environment. Photographs from this project are on display at the National Academy of Sciences (2100 C St. NW) through Sept. 28. Free. Open weekdays from 9 a.m. to 5 p.m.; photo ID required. 202/334-2436. www.nasonline.org.
