Royal Air Force: No 1 Camouflage Unit (Scotland)
Scope and Content
Administrative / Biographical History
No. 1 CAM unit was responsible for collecting vertical and oblique survey cover of the United Kingdom during the Second World War (1939-1945) using mainly training aircraft. Large tracts of the country were photographed to monitor the effectiveness of various camouflage schemes and to provide cover of possible invasion beaches on the eastern seaboard. In particular the photographs were used to assist in the camouflaging of industrial plant, airfields and other installations vital to the war effort. A number of the oblique photographs for Scotland have survived and are contained in this collection.
The CAM obliques, taken for strategic reasons as well as to test equipment, rarely covered military targets. The material is mainly concerned with the central belt of Scotland due to the greater industrial concentrations under threat from enemy activity and in need of camouflage appraisal.
These aerial photographs represent a small selection of the total created during the wartime operations of No. 1 CAM Unit. The original negatives of these prints were deliberately destroyed during the 1950s after their chemistry had become unsafe due to their nitrate base. Many of the prints still retain their 'chinagraph' pencil marking where photo-interpreters have annotated 'features of note'.
