Hello
I know of a way of producting color images directly on glass plates
called "autochrome". Been invented at the beginning of the century by the
Lumieres, the following site
(http://www.institut-lumiere.org/francais/lumiere/sautochrome.html) explains
--in french-- the development of this technology (based on colored potato
starch grains) to obtain a means of capturing color without the 3 filtered
exposures. As explained on the page, the image is a *positive*.
or go there: http://www.bway.net/~jscruggs/index3.html and choose 'autochrome'
in the left menu.
In France, the Albert Kahn Foundation has apparently a
collection of 72 000 autochromes, done between 1910 and 1931, recording
various subjects from the whole world, and especially France, in the
followin areas: everyday life, habitat, industry, military, war
etc...on command by A.Kahn (a banker and philanthroper in the XIXth
century). It can be visited, but only on arrangement.
From the few that I have seen, grain is quite perceptible, but the colors
show no shifting (or wrong dominant) AT ALL, though they have sort of a
pastel-like softness, which for a 100-year picture is quite a remarkable
performance.
I think later there was color film (movies) based on the same
kind of materials.
cheers.
