INSTRUMENT CAMERA FOR AIRCRAFT
R. H. Field · Canadian Journal of Research/Canadian journal of research · 1944
The camera is intended for photographing at regular predetermined intervals, or at desired instants, a number of instrument dials contained within the camera base. Records are made on 35 mm. film. The magazine is small and easily detachable to permit loading and unloading. Exposure is obtained by flashing lights, thus eliminating the need for a shutter. After each exposure the film is automatically reset.
