30/73 Coop Cinema Amsterdam 50 years old

Kren shows the cinema (mentioned in the title) during and after film presentations. He uses single-frame and time exposures 5 to 30 seconds long. Sometimes sunlight comes through the open door into the theater changing the colors in the film remarkably. Black spots appear when the lights inside the cinema are turned off. The film is uncut and was recorded with a shoulder tripod over a period of three weeks.
