The Kodachrome Process for Amateur Cinematography in Natural Colors

The new Kodachrome reversal process is a three-color subtractive process, the colors being formed by combining the three complementary or “minus” colors, which absorb the corresponding primary colors from the projection beam. There are three emulsion layers, separated by thin layers of clear gelatin, the first layer being sensitized to blue, the second to green, and the third to red light. — The film is exposed in the ordinary manner, with the emulsion toward the lens. Processing is done by the reversal process, and the three positive images are their differentially dyed the three corresponding minus colors. The finished Kodachrome film is projected in the usual manner, without filters.
