Any idea what kind of materials should I use?

Danger: My initial plan was to create a mirror which will reflect a B&W image, instead of color. But I would be happy ig I could make a simple B&W image without using any electrical stuff.

Chroot, you said that the filter should be able to add frequencies together. Is there any physical way to accomplish this? For example to separate the image on 3 channels and then add their frequencies together?

Chroot, What do you think about Danger's preposition?

Mech_Engineer, a b&w film works different. The film has some kind of grains on it, which are light-sensitive. As soon as the lighting strikes over them, they can't "reset" anymore. I want to be able to see through those filters or whatever it is, and see a b&w representation. I don't need a...

Danger, I had a similar idea, too. But chroot said that a physical filter only removes frequencies from its input. I think that this will produce a totally white image. Am I right or...? I was actually imagining as if the picture passing thorugh a monochromator, it separates the different...

What if it is somehow possible to get equal value for R, G and B? I'm not sure whether this works in the real physical world, but I know that a color with a value RGB 50/50/50 (or simply said x/x/x) is a greyish color.

I forgot to give the link for the monochromator: http://en.wikipedia.org/wiki/Monochromator

Hi to all! I have a little question for you. Does a b&w glass filter exist? I now there are all kind of color glass filters, but I want to know if there are any possibilities to generate a b&w image without using your camera or your computer. I know about the monochromator device, but it...
