In spring and summer 1866, having purchased a new, larger camera, Cameron produced a series of 12 “life-sized heads,” including this angelic study. Throughout her work, poetic truth was valued above photographic truthfulness. She conveyed a sense of life and breath and of honest emotion through careful lighting, shallow depth of field, and soft focus. “My first successes in my out-of-focus pictures were a fluke,” Cameron wrote. “That is to say, that when focusing and coming to something which, to my eye, was very beautiful, I stopped there instead of screwing on the lens to the more definite focus which all other photographers insist on.”
