Document Summary

Enlargers - projectors equipped with a variable stop and exposure timing to control the amount of light projected. 9. 2 color versus wavelength, and non spectral colors. Colors are not generally identified with a unique wavelength. Monochromatic or spectral light consists of only one wavelength. 9. 3 the intensity-distribution curve and the classification of colors. Intensity-distribution curve - measure intensity at each visible wavelength and plot the result. The three qualities of colored light that determine how that light will appear are hue, saturation, and brightness. Hue - main color or color name, distingue spectral colors, specified by dominant wavelength on light curve. Situation is a measure of how much dominant wavelength there is compared to the amount of white mixed in. Brightness - overall sensation of the intensity of light. Lightness - reacted to the percentage of incident light reflected by a surface and refers to the blackness, grayness, or whiteness, of a color.
