Zed Nelson is a photographer living in London. The idea came back in 1991 when a friend of his was 9 months pregnant: photograph the same subject, in this case a family, with the same conditions (lighting, background, etc.) at the same day and time of each year. The series was based on the time-lapse photography as his main concern was to capture the growth through time of the people engaged. The photographer captured time. This rare and the result is wonderful.
