Notes on this view:

Kodachrome, introduced in 1935, was the first commercially successful chromogenic color process. A Kodachrome transparency, or slide, is a one-of-a-kind direct positive image. It is composed of three superimposed gelatin layers each containing a subtractive (cyan, magenta, yellow) dye image on a clear plastic support. The bottom layer contains a cyan dye image, the middle layer contains a magenta dye image, and the top layer contains a yellow dye image. The result is a positive image on a transparent support, which is intended to be viewed using transmitted light.
