what kind of filters can I use?

I guess you are talking about filters for B&W film, right? If your lens is threaded on the front to accept filters, you can either measure it or take it to the camera store to see what fits. If it isn't threaded, you might be able to use a press-on series adaptor or a compendium with a built-in gel holder. A pro camera store should be able to help you figure it out.

I don't know if colored filters work the same for B&W reversal movie film as for B&W negative film, but a good general reference about using filters effectively is "Using Filters" from the Kodak Workshop Series.

Monobath answer was a good one. You need to have a basic understanding of what the different filters do, and filter factors.

A quick run down on some black and white filters.

Red - works well for day for night and turning sky black or very dark. Skin can look a little pasty. Red filters pass red light and hold back (read darken light from the opposite color range, like Blues.)

Orange less sever than Red. I like the Orange filters for water and sky shots. You might even try shooting black and white with your 85.

Yellow - good all purpose filter to make sky look a little darker and improve flesh tones.

Greens. Lightens foliages makes sky lighter. Some people like this on wood. and to hide bad complexion. This filter has never been one of my favorites.

Each filter has a different filter factor. You will need to open the lens to compensate for filter light loss.

Before you spend a lot of money on filters on E/Bay consider that your cameras may change, you may not want to be locked into a round filter that may not work on your next lens or camera. Consider going to a 3x3 or 3.4 filters or large. and using a Matt box / filter holder. If you think out your needs you can get filters and a lens shade system that work with all your cameras or future needs.

One of the most useful filters for color or black and white photography is a ND grad. That way you can pull down overexposed sky without underexposing faces or foreground action.

You should also have a set of ND's 3 stops, 2 stops and 1 stop, so you can lower light levels and keep shooting at the same F stop for greater scene to scene consistency and ND's will allow you to shoot at your camera's sharpest lens opening.

Each lens has it's own ''Sweet spot." and F- stop that kicks maximum resolution. It's usually That lens opening is usually about 3 stops, but not always about three stops closed down, from wide open. Run a test on each of your lens and find out first hand.

You could also get a combination filter of a 85 and ND...So you only need to buy one set of filters. But the down side is if you shoot in Black and White, you should go with straight ND's

For now stay away from the artsy filters.
Fogs, Double Fogs and Diffusion. In most cases you will like sharper imaging in
Super 8, not less.

I want to start using yellow blue and green filters. Since I know nothing about filters, I was wondering what kind of filters I can get for my canon 814. Are there specific ones or just the same ones they use for 35mm still photography. I was on ebay looking for some but I don't know what's what. Thanks
