Abstract

The artificial color definition of gray-scale levels has progressed through a number of evolutionary steps which started with early efforts to "color-label" the high-, medium- and low-intensity tone levels of infra red films. The three-layer color-composite, when registered and projected on a viewing screen, provided some coarse but readily recognizable bench marks for the gray-scale values of an image. While a three-point index spread over a wide range of image intensity was a rather crude and inflexible form of scaling indication, it was, neverthe-less, the first step in the right direction. Multispectral photographs provide distinctive information about ground terrain, from aerial views and when the individual spectral responses are encoded by projection through colored filters, the composite result may be registered and viewed on a common viewing screen.
