“Aperture: Photographs,” the latest art installation to open at the Former Spanish Ambassador’s Residence, follows the history of the Aperture Foundation, founded by American photographer Minor White in 1952 to celebrate the art form, with photos that span 50 years of the foundation’s magazine. Unsurprisingly, the exhibition is the cornerstone of the annual photography festival FotoWeekDC: The 90-work exhibit covers an enormous range of material, stretching from the early 1900s to present-day pieces. Among the artists featured are Depression-era photojournalist Dorothea Lange, contemporary portrait photographer Annie Leibovitz, Hungarian war photographer Robert Capa, and dozens of other influential individuals.
