Very high resolution aerial films

Abstract

The use of very high resolution aerial films in the aerial photography practice is evaluated. Comparisons are made between commonly used panchromatic, colour and CIR films and their high resolution equivalents. Based on practical experience and systematic investigations, this paper demonstrates the very high image quality and improved height accuracy that can be achieved using these films. It evaluates the advantages to be gained from this improvement and discusses the present operational restrictions encountered when using high resolution film materials.
