Autochromes
The autochrome is the first commercial process for colour photography, discovered by the Lumière brothers in the early 1900's.
"The principle consists in using a color filter made of microscopic grains of potato starch (6,000-7,000 per square millimeter), colored in orange, green & purple. The filter is spread on a glass plate which is then protected with a varnish & covered with a black & white photosensitive emulsion." (Alain Scheibli)
The colors in an autochrome have a distinctively different feeling than conventional color photography. It has a somewhat other wordly atmosphere which I feel is an excellent compliment when used with pinhole photography. I've adapted this technique to be able to do it on the computer.
