For his latest project titled "Faces Of Century", photographer Jan Langer took photos of over a dozen Czech centenarians and compared their portraits of when they were young, and when they were over 100 years old. "This set of comparative photos explores the similarities and the differences in appearance and in physiognomy," Langer writes about his project. "The characteristics of personality change throughout life but it seems as if individual nature remains rooted in the abyss of time."
