When I was child my camera was the cheapest one. And I had to rewind a film manually. Of course I very often forgot to do so. So several shot were taken on the same frame. Then I was disappointed and considered them as lost. Now I have a different opinion. I remember with nostalgia those unpredictable effects created by this. I have found Pentax digital camera which can take several shots on one frame and do such shots on purpose. This one is taken from the roof of the Crown Plaza hotel in Brussels.
