Yes Umut, of course I've read it.

You ask, "Second , can trichrome photography could be done with color film , is it suitable for that ?". That's a rather open ended question. I mean, for one, it already is trichrome photography. Do you mean utilizing the color film as the screen-plate emulsion? Do you mean making filters with color film? Do you mean making 3 separate exposures through filters onto 1 sheet of color film?
