No. 4 - How hipsters make coffee, and photographs.
Okay fine, haters, it's interesting. :) It's depth-dependent wavelength encoding. I never learned about this in a History of Photography course that included a visitor who made a daguerreotype of me in a Civil War uniform. It sounds like a physical, 3D spectrum analysis (2D to physical, 1D to wavelength)
The now extinct Kodachrome color K-14 process is also interesting because the colors last longer than early negatives of generic color film E-6 processes, the kind my grandparents took. Does anyone know why K-14 went away? Did the developing chemicals expire rapidly?
- exmadscientist 5y agoIt seems K14 was very, very different from all other common processes, according to the guy who figured out how to do it himself: https://emulsive.org/articles/darkroom/developing-film/they-took-my-kodachrome-away-so-i-brought-it-back https://emulsive.org/articles/darkroom/developing-film/they-... > Kodachrome’s K-14 process is quite unlike any other. You see, Kodachrome isn’t ACTUALLY a color film, it’s several layers of black and white film sensitized to the different colors and the necessary color dyes are added during the development process. This involves....
- failwhaleshark 5y agoYep. Similar to the OP article in the sense of different and more complicated than the E-6 process.
- ginko 5y agoThe Kodachrome process was very complicated. While you can develop E-6 with just 3 baths you need several development and exposure steps to do K-14. Here's an illustration: https://miro.medium.com/proxy/1*w0fPDTcXMkMzSsVHQgGWrw.gif https://miro.medium.com/proxy/1*w0fPDTcXMkMzSsVHQgGWrw.gif The chemistry is apparently quite complicated and unstable as well with film labs requiring a dedicated chemist to keep everything in check. It's not one set-and-mostly-forget developing machine in your back room like with C-41 color negatives.
