Summary: Army Instructional film emphasising the importance of camouflage. A German Messerschmitt 110 aircraft photographs British positions, easily visible due to poor concealment. The film demonstrates proper camouflage techniques and shows how an army can adapt itself to fit in with the natural pattern of the landscape. Each error spotted by the German aircraft is corrected with reference to the siting of equipment and positions and the disguise of potentially revealing shape, shine and shadow.
