On day 12 we continued to talk about subtractive mixing with filters. We covered the following topics
- Subtractive mixing with filters
- Transmittance curves
- Ideal vs real fiters
- Cyan, Magenta, and Yellow (CMY) color system
- We also touched on color photography (and in particular the work of the physicist J. C. Maxwell) the early color films, including the two-color system and the three-color Technicolor system. We saw a nice example of early film created using the two-color system, for which the camera had rapidly changing red and green filters.
