Microscopy of Historical Film Colors The exhibition Microscopy of Historical Film Colors was an event that showcased a project that examined historical film color samples and the chemical composition of these cross-sections. This event was a perfect example of the applications of this class, as it carefully examined the science behind an artistic production. One of the examples presented that stood out to me was mordant toning. Mordant toning is a technique that replaces silver images with colored dye (filmcolors). This technique was created in order to broaden and intensify the range of colors in films. In this method of toning, the silver in the image is chemically converted to a salt that is essentially colorless, and therefore serves as a mordant (FilmCare). It can then be dyed with solutions to enhance the picture, and as a result, produce better imaging for films (PR). I found this interesting because of the exact scientific process behind ...
