The photographs were made in Denmark during a sandstorm. The sand flying around could not harm the
camera, because it was a black box with a tiny hole: a pinhole camera. Seeing the big black box half buried in the sand passing people asked me if I did some geological investigations. I stood nearby the camera waiting up to 30 minutes, this was the exposure time. In the darkroom I found a lot of sand inside the camera. It had found its way through the tine hole during the exposure.
