Growing awareness of aerial photography led to an increase in militaries using camouflage techniques and related tactics to conceal and divert attention away from their various activities. Steichen commented that “recent camouflage development has been a constant race to keep up with the work of the photographic observers, the visual observers having been left far in the rear.” To combat this deception, photographers used panchromatic film (which is sensitive to all wavelengths of visible light) and filters and photographed at varying heights, angles, and lighting conditions. Stereoscopy was also a highly coveted tool, as it provided a three-dimensional view of the terrain.
