Now, a new technique has been developed to obtain good quality photos at low cost & with minimum delay. Instead of using expensivf cameras fitted to special photo-aircraft, small format, low cost 70mm cameras are fitted to commonly available light aircraft. For example, a single Hasselblad c!lfra or a multi-spectral system can be mounted onto the outsidf of a range of Cessna aircraft.
