When the wThite light from the projector traverses the film, the blue rays are absorbed by the yellow (minus blue) dye, and the red rays are absorbed by the cyan (minus red) dye. The only portion of the white light that remains unaffected is green; in this manner the green light used to photograph the original scene is reproduced by the film that is run in the projector. The reproduction of red is accomplished in a similar manner. If only red light was used to expose the film when it was placed in the TABLE IV Color Reversal Films for Original Photographing For Direct Projection Manufacturer Code# Trade name K color temp.

The top and middle layers, being unexposed, are dyed yellow and magenta, respectively. When the white light from the projector traverses the film, the blue rays are absorbed by the yellow (minus blue) dye, and the green rays are absorbed by the magenta (minus green) dye. The only portion of the white light remaining unaffected is red ; in this way the red light used to photograph the original scene is reproduced by the film that is run in the projector. Since all colors are made up of these three components in varying degrees, any color appearing in nature can theoretically be reproduced. Table IV is a list of some common color reversal films for original photographing.
