CHAPTER 12 COLOR  PRINTING The mechanics of color printing are similar to black-and-white printing. Once you have mastered the techniques  of  black-and-white  printing,  you  will  have  a solid foundation to build your knowledge and skills in color printing. The most difficult task in color printing is  distinguishing  between  various  and  sometimes  subtle colors and selecting filters to produce a color balanced print. That is not as difficult as it may sound. Through time  and  practice,  you  will  make  excellent  color  prints; however,  before  color  printing  is  discussed,  the principles of color photography and how they apply to color  printing  will  be  reviewed. PRINCIPLES OF COLOR PHOTOGRAPHY Most   people   see   in   color   and   expect   their photographs  to  be  in  color.  Because  of  customer demands   and   the   cost   benefits   involved,   color photography has nearly replaced black-and-white photography in Navy imaging facilities. Few amateur photographers understand the complexity of color reproduction in color photography. Most of these amateurs take their unprocessed film to a drug store or a 1-hour photo finisher. As a Navy Photographer’s Mate, you  are  a  professional.  To  produce  professional  quality color photographs, you must have a basic understanding of the color process. Usually white is thought of as no color; however, it is more accurate to think of it as all colors. When one of the colors is absent, the color is not white light, but a different color-green, for example. When magenta (a bluish red color) is absent, the resulting color is green. When cyan (a greenish blue color) is absent, the color is red, and so forth. As you read this chapter and when you color print, you may find it helpful to think of a color as white with something  missing;  that  is, blue  is  minus  yellow; green  is  minus  magenta; red is minus cyan; yellow is minus blue; magenta is minus green; and cyan is minus red. Also keep in mind that all color is light; and white is all colors. COLOR IS LIGHT The color you see is simply light. Where there is no light, there is no color. When you “see” a colored object, what you are actually seeing is the light reflected or emitted from that object; therefore, the light alone is what you see and not the actual object. The color of light people are most familiar with is white. Actually, white light is made up of all the colors, although they are impossible to see directly. When you see white light reflected from a sheet of white paper, you are actually seeing an equal mixture of red, green, and blue light being reflected in equal amounts. You must realize  and  understand  this  fact  before  you  print  color. LIGHT   PRIMARIES White light is a mixture of all the colors of light; however,  only  three  primary  colors  are  actually  needed to make white light. These three primary colors are red, green, and blue. Not only do these three light primaries produce white light, but they produce any and all other colors; for example, imagine a blue, a green, and a red spotlight  shining  on  a  white  screen  so  the  spotlight circles  partly  overlap.  There  are  three  places  where  two of the light primaries overlap and one place where all three light primaries overlap. In the areas where two primaries overlap, a distinctly new color is created 12-1
