Hi,
My good friend Henri Gaud try to rediscover colour photography by
direct trichromy ....
He achieved successfully fine colour 8"x10"photographs, with triX film
sheets.
The first theoric issue is here:

and his blog is very active:

The text is in french, but let's see the photographic results!
regards
Christophe
