The best architecture photographers use light and perspective to elevate what could be static images into single-frame movies, documenting places as organisms full of verve, mystery, and life. Ezra Stoller might be the first name in the architectural photography conversation, but PBS’ American Masters series makes a strong case that it should be Pedro E. Guerrero.

The inspiring, albeit limited, 60-minute documentary profile Pedro E. Guerrero: A Photographer’s Journey, which aired Friday, September 18 and can be viewed online at PBS.org, introduces us to a photographer who deserves far greater recognition. (Google “Pedro Guerrero” and most of the first two pages of results are about a former baseball player with that name.) Guerrero, who began his career as a 22-year-old amateur with no architectural knowledge, ultimately made his name chronicling Frank Lloyd Wright’s projects and, later, mid-century interiors and the work of artists Alexander Calder and Louise Nevelson. But it’s his work with Wright that would define him—and, to an extent, Wright.
