Kodachrome - Chemistry and process - a personal discovery

[ZoneV]

Years ago when I was in middle school, I picked up a Chemistry textbook that I found in the house, and started looking through it. Inside, on the very last page behind the rear cover, was a color diagram of the Kodachrome process. I was intrigued by this since I was into photography, and studied that diagram in detail. I thought it was interesting how the film development had so many steps, and that it had to be exposed to different color lights in the process. I decided right then and there that I was eventually going to try Kodachrome film.

The book, a classic Chemistry textbook by Linus Pauling, can be seen here thanks to Google Books: http://books.google.com/books?id=Epx...sult#PPA971,M1

Check out the second to last page (971) for the diagram of the Kodachrome process. Link to schematic: http://books.google.com/books?id=Epx...search_s&cad=0

Very interesting! I had been aware that there were different colored developers required, but not the exposure to different colored lights. I can see why this process isn't popular in this day and age. It makes me appreciate the Kodachrome and Dwaynes that much more!
