It is helpful for you to think of color paper in terms of its three separate emulsion layers. Each of
the layers is sensitive to light of a particular color (blue, green, or red). Each of the layers must receive
the correct exposure in order to produce a print of satisfactory density and color balance. A change in
the overall exposure time affects all three of the dye images, while a change in filters and its strength
will affect the exposure of one or two emulsion layers. By manipulating these variables, you can control
the density and the overall color balance of the print.
