Childhood as a self-willed process is the central theme of 2 One Child by Berlin photographer Eva Bertram. Over a period of eleven years, Bertram photographed her daughter, Herveva. The pictures not only depict the astonishingly theatrical changes in the girl, but also reflect the special relationship between the photographer and her model, as well as the increasing recognition of the daughter as an independent person.

A selection of around 70 photos of the girl often shows her amid installations and playing fields she made herself. At the same time, the playful quality of her poses and arrangements is also part of the girl's serious role-playing. In this situation the photographer regards herself as an observer of childhood processes, which develop their own independent dynamic through the camera, so that performative play increasingly becomes performance and presentation.
