Lumiere Tri-Chromie Process
The Tri-Chromie or three-color process basically uses black and white panchromatic film with three different colored filters to achieve a multi-colored image. The Lumiere Tri-Chromie process dates from about 1893. It was part of their color experimentation that eventually led to the Autochrome. It is not believed that the Tri-Chromie process was never sold commercially.
