Baltimore-based photographer Jack Radcliffe started taking pictures of his daughter Alison shortly after her birth at Johns Hopkins Hospital in 1975. That’s nothing unusual; what is remarkable is that Radcliffe never stopped aiming his lens at his daughter, capturing her in black lipstick and dramatic eyeliner at age 15, smoking with her long-haired boyfriend at 16, looking sad with a shaved head at 20, eating at the Golden West at age 36. It’s remarkable to view the metamorphosis of a face — and of a person — over time.

“My photographs of Alison, because of the nature of our relationship, are very much a father-daughter collaboration-Alison permitting me access to private moments of our life, which might, under different circumstances, be off-limits to a parent. The camera, early in her life, became part of our relationship, necessitating in me an acceptance, a quietness,” Radcliffe writes. Some of our favorite images are below.
