Edward Land began devising his Poloroid glasses just before World War II. As the Army Air Force needed to find ways to detect elevation, he helped them develop 3-D technology that first was used in bombing over Germany and then in the Pacific beginning with tests in the Aleutians. The reconnaissance planes began taking extensive aerial photographs of the Mariana Islands with an emphasis on Guam. General Haywood Hansell helped as the 3-D models prepared the way for the invasion of Guam and eventually Japan where the details helped B-29 crews in the Pacific recognize every steam, hill and industrial target in the Nipponest homeland. (see the Evaluation of Photographic Intelligence in the Japanese Homeland, Part One and Two. [Washington] Photographic Intelligence Section]. Here is the photographic image of Guam, the enhanced image drawn up by the 947th Engineer AVN entitled: "The B-29s on Guam". The photographs measuring 4 3/4" x 3 1/2" show Apra Harbor in September 1945 and four additional photographs of the native huts and people. Included are a pair of Poloroid three-dimensional picture glasses and a glass frame 3-D Picture Viewer. The case for the glasses frame has become firmly glued to the original film image but the map can be seen in the film of Guam.
