This Kodak 75 x 75mm #34A Violet Filter is a solid-colored contrast filter primarily designed for minus-green and plus-blue separation, such as with the Kodak Fluorescence Process.
Wratten 2 filters are constructed from gelatin for ease of use and consistent performance. When compared to original Wratten filters, Wratten 2 filters are more rigid and durable, easier to handle, and less sensitive to humidity, static cling, and fingerprints.
Solid violet filter is designed for minus-blue and plus-green separation processes.
