It could work with any three filters, BUT the color gamut will be different and the closer the three filters you use are to being monochromatic, the wider range of colors you will get.
If you use the 29, 61, and 47, you will get a standard RGB separation set that you could at one point take to any lab in the world and get a composite color print made. If you use some other filters, you will not necessarily have colors that translate to the primary colors the lab printer uses. This means you will get things like skin tones that are fine when the whites are green.... and if you time for the whites to be white, the skin tones go magenta.... because the colors the lab is using for the three primary colors are not the same as the ones you pulled the separations with. If you're using a different set of filters than standard, be sure to very carefully document everything and mark all the leaders. If you are attempting to project through filters, mark each film about how it should be projected and expect to regularly replace the filters because they will fade. I don't know the 47B offhand, but you can get a set of gelatin tricolor filters from the Kodak motion picture division if you can figure out the order numbers because they aren't in the H-1 book anymore. You might be able to get them from a graphic arts supply house too. --scott _______________________________________________ FrameWorks mailing list [email protected] https://mailman-mail5.webfaction.com/listinfo/frameworks
