Chapter 1. Perimetric color photography
Perimetry is a method that allows you to record changes in the color rendering of light in a limited area along a certain direction. Currently, the perimetric method is widely used to record the spectral characteristics of radiation from natural objects of various types and therefore has become the basis for the creation of color methods for diagnosing the state of the environment.
Spectrophotometers of various types can be used as instruments that implement this method, for example, horizontal spectrocolorimeters described
