ABSTRACT
Image components are separations of an image into distinct color or tone parts. When all three of the light components are switched on, the red, green, and blue components combine to re-create the full-color image from the three separate black-and-white components. Filtering works to put the color into the people image, but a lesson learned from Prokudin-Gorskii is that light components can also be filtered out and separated from color images. Using separated components as described in the chapter gives the people tremendous flexibility with the application of components in a more straightforward model than using Channels or channel functions. There is a lot to explore in standard separations of RGB, CMYK, luminosity, and color and perhaps even more to explore with custom separations.
