- All film stock fades. Even with modern chemistry film fades. Even if you store it in darkness at the proper temperature and humidity it fades. Archivists are very concerned about this and companies like Kodak are working on the problem, but if you want film to last, then it has to be in black and white. Wait, I take that last statement back. Magnetic storing and digital storage in general will last as well. -Marty Sasaki

Indeed, all color film fades. But many old color movies (particularly Disney flicks) still have perfect color. Why? Because they were done originally in three-strip Technicolor or stored in separation: in either case, the three colors from each frame are maintained in black-and-white.

That's so whole point of the Technicolor separations. Storing as three black and white separations means prints made today are just as (if not more) vivid than prints made at the release time of the movie. -Ron

Seems like color film compares pretty well to that.

True, black-and-white film stock will not deteriorate at nearly as fast a rate as color film, but eventually, b&w film stock will also "fade".

Several years ago I saw a clip of the first Technicolor film done in circa 1930 with Eddie Cantor. It was just as good as any 35mm film done today. The colors were bright and vivid and the whites were just slightly toward blue. The original Technicolor process used a 35mm Mitchell camera with 3 film gates, side by side, and a prism to seperate the received image into three paths. A color filter was used in each optical path to seperate the images into the primary colors. Because of the optics and filtering greater light and more consistant color temperature had to be used. Prints were made using the three negatives using a step printing technique and dye transfer. The negatives were standard b&w stock. Dave Williams Tektronix, Inc. ECS

#R:harvard:-24800:wdl1:1500002:000:312 wdl1!jrb May 17 11:24:00 1984 The answer is to do a dye-transfer 3-colour separation (as was done for The Empire Strikes Back). The problem is that is expensive and there is only one place in the world that does them (and it's in China). John R Blaker UUCP: ...!fortune!wdl1!jrb ARPA: jrb@FORD-WDL1 blaker@FORD-WDL2
