On CIR images near infra red range of electromagnetic radiation is registered. In this range the difference between reflectance of terrain objects and trees species becomes more clear. Three digital images corresponding to the component colors in RGB were obtained by scanning analog images. The colors represent intensity of solar radiation recorded on the image. Digital recording is considered an objective representation of the color phenomenon. The paper presents digital analysis of classification of tree crown (spruce) results for three health levels, carried out by using visual method, by different operators. It was found out that the results were widely dispersed. The interpreted categories were also equivocal, because trees with the same color code were included to different health levels.
