The idea of using photography and slide projection is based on the inherent possibility of this medium that enables us to cover up with its help in a very banal and explicit way one object of our surroundings with the image of another one. A photograph in our everyday life, while showing us something, it also necessarily covers one part of our reality. In my procedure this covering up takes place more directly than in the case of a normal piece of printed picture, because there is no frame -- neither physical nor conceptual -- to really legitimate the presence of the image that „cuts” into the surface of the real objects. The projected picture appears thus somewhat unexpectedly, as a clandestine element within its new surroundings, one could say.
