Description

Process for still photography in which light is filtered through a screen or transparent plate covered in lines or dots in the primary colors orange, green and violet. For the positive, the process relies on a support material which includes an emulsion and, underneath, the same screen of lines or dots colored blue, red and yellow respectively. On this support, three thin layers of gelatin with their corresponding colors are poured.
