We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
NOW YOU SEE IT. Before the camouflage experts went to work, this factory — a model, for test purposes— was photographed from the air on conventional panchromatic film. The bomber's eye would see what you see— a perfect set-up for destruction.
NOW YOU DON'T. With camouflage materials — false structures, netting, cloth streamers, paint, and artificial trees — the experts have fooled the camera, and the bombardier. To the aerial camera loaded with panchromatic film, even the marks of erosion on the slope by the railroad track have disappeared.
Infrared Film spots the "make lelieve" of enemy camouflage
G
CAMOUFLAGE is the highly developed art of pulling the wool over an enemy's eyes ... an art which is finding old methods ineffectual, in this war.
This is in a measure due to Kodak's development of a type of film whose vision goes far beyond that of the human eye.
Natural grass and foliage contain chlorophyll — Nature's coloring matter. Camouflage materials lack this living substance. Chlorophyll reflects invisible infrared light rays — and Kodak Infrared Film registers this invisible light, making the natural areas look light in the picture — almost white. In violent contrast, the "dead" camouflaged areas show up dark — almost black — in the picture.
Moreover, Infrared Film is able to penetrate through the haze of a "low-visibility" day, and return from a reconnaissance flight with pictures in clear detail. Here again it far exceeds the power of the human eye.

Working with our Army and Navy flyers and technicians, Kodak has carried this new technique of camouflage detection to high efficiency— and has, for our own use, helped develop camouflage which defies detection . . . Eastman Kodak Company, Rochester, N. Y.
BUT HERE IT IS AGAIN. With Kodak Infrared Film in the aerial cameras, pictures like this are brought back from an observation flight. On Infrared pictures, the false, "dead" camouflage materials look almost black. The natural landscape is unnaturally light. A trained cameraman, with one look, knows where the bombs should strike.
