Tempelhof was an International Airport in Berlin (no longer operating). The Berlin airlift (which began June 26, 1948 and lasted until May 12, 1949) was undertaken during the Cold War by the United States and their allies in Western Europe to transport humanitarian aid to West Berlin, which had become a dark city under siege without food or medicines, since it was surrounded and isolated by the Soviets. The work proposed here aims to remember that sky. This image is part of a series of analogic photographs whose negatives are then scanned and the resulting file pigment ink-jet printed on cotton paper Fine Art. The peculiarity of this series ("Contamination"), compared to the rest of my negative production, investigate the problem of the identity of the instrument, poised between the film and the digital file, between the chemical development and the ink-jet printing, including the paper that wraps the film (here seen in its "contamination" of the film ) and the media, which can accommodate the final image (not just fine art paper, but rather a screen, or any body surface area).
