I've seen some pretty good results with color corrections filters. At least from the screenshots I've seen here. I'm wondering, would it be possible to apply a dye directly to the film to correct the color at the source? In essence, revitalize the film?

I don't know enough about chemistry to know what would adhere but if it's a translucent piece of blue that sits in front of the lens to correct the color, couldn't you localize the same principle to the film itself? It would spare the need for a filter and the dye process could potentially be tailored specific for a certain film's level of color loss.

I'd imagine it would be something that could be applied with a rubber dry transfer roller and you'd need to be careful in the drying process so as to not warp the film.

Though I know magnetic tape in general can't get any moisture on it. So maybe it would ruin the mag stripe?

I suppose it might be possible to do, but the level of work that would be required to get this colored covering to adhere to the entire film (not too mention every film you have that has faded)securely would seem impractical. Especially when you begin to consider things like thickness (Is it going to make a 400 ft reel spill over)(Is it going to get stuck in the closed Eumig sound sections)

Or if you were thinking of dying the film with some sort of liquid, take it from someone who has done a great deal of experimenting with tinting my old silent films. The level of machinery that would be required to get the dye to adhere to the film completely evenly all throughout would need to be engineered with such precision calibration it would be cost prohibitive for anyone attempting such a venture.

I think popping a little colored filter onto the lens is just too easy compared to the alternative.

I agree with Dino, though I have longed to try just what you are considering.

I don't know how hard it would be to dig up, but many years ago, someone showed actual blue-prints for a machine that would actually do this, but I don't know if the patent owner ever built one in anything but theory ...

could someone who's in the know, find that very old post? It has to be around ten years old or so.
