"Tilbakeblikk" is the name of a joint project between the Norwegian Forest and Landscape Institute and Norsk Folkemuseum. Tilbakeblikk means “retrospect” or “looking back” in Norwegian, describing the project’s use of photographs taken of the same places separated by long periods of time to illustrate landscape changes in Norway.
