This camera has only USAAF numbers and markings. The K-series camera appears to have been the model of aerial camera favoured by the USAAF during the interwar period 1920-1942 Aerial photography has been used "for mapping charting of the sea coasts building of highways town planning and any ground activity where a measure of size or change must be made. Aerial photography provided the first true measure of the size and physical makeup of the surface of Canada. It has played a vital role in major engineering developments such as the Trans-Canada Highway and the St. Lawrence Seaway. Aerial photography proved invaluable in the opening of the North and in the evaluation of Canada's forest resources." | Aerial photography. | When the US entered WW2 the K-3 (Graflex/Fairchild) was replaced by the improved K-17 model. The K-17 has a shorter focal length than later cameras and was used for lower altitude reconnaissance in faster fighter aircraft (e.g. P-38). It appears that most of the patents found on the camera were assigned to the Fairchild Aviation Corp.; however both Graflex and Fairchild built these cameras. | Photography | Still cameras | Specialized | Exploration and Survey | Photogrammetry | Photographic equipment | Aviation | Miscellaneous | metal->steel;glass->;synthetic->;skin->leather;fibre | 50 | 44 | 31.5 | http://source.techno-science.ca/artifacts-artefacts/images/1966.0048.001.aa.cs.png | http://source.techno-science.ca/artifacts-artefacts/images/1966.0048.001.aa.cs.thumb.png |
