What are all the camera filters and what do they do? (Girlfriend wants to know.)?For digital SLR cameras. Is there a list or something on a website? Are there picture examples? Thanks.

There are only a few filters necessary for your DSLR
* UV or skylight to protect the front element of your lens
* Polarizing lens for landscapes.
* ND filters to allow long exposures in bright sun
* IR filters (may or may not work on your DSLR depending upon the design of the camera's sensor)
All colour correction is done using the menu on the camera using the white balance adjustment for your camera

Starting at the most useful ones...
1. Polarizing filter-reduces polarized light (gets rid of most reflections and glare besides metallic surfaces), so if you were shooting into a lake, reflections would be reduced and you could see more clearly through it. But if you applied that to, say, a chrome muffler on a motorcycle, then nothing would happen, because that's a metallic surface. It also deeply darkens blue skies, which is a very desireable effect.
2. Neutral Density-this darkens the image so that you can use slower shutter speeds while still retaining the same exposure. The longer the shutter speed (time the camera shutter is open) the more time the light strikes the sensor. This is how motion blur occurs-the shutter is open during the motion in question, so it captures that motion (say somebody moves during a family portrait, and you notice on the final picture that it looks blurry and weird, and is in a different position). So, say you wanted to blur a waterfall (again, a desireable effect), you could use a longer shutter speed (motion blur). Of course, because there's more light striking it for a longer time, it will appear blurry, but it will also be too bright. ND filters darken the image, so it can be blurry, but the filter is automatically darker. So, instead of going from normal brightness to too bright, it goes from too dark to normal brightness. When people shoot a lot, it becomes much more useful to them.
3. UV filter-reduces haze and is basically transparent and very cheap, so it is often used to protect the camera lens from scratches. Reducing haze is especially useful in landscape situations, where long distances produce haze on the horizon. you can clear this up via a UV filter.
4. Warm-Up Filter: This is usually only used in film. It is used to create warmer tones in an image, which is much more pleasing to the eye. You can achieve this via computer editing (photoshop, as an example) thanks to digital imaging.
5. color filters-this is primarily used in black and white photos, because it causes a specific color to stand out.
Say you weer shooting B&W, in a field of yellow flowers. You all of a sudden find a small patch of red flowers. To make these red flowers stand out in black and white, you could use a red filter. Basically put, it makes all colors bland and midtone except for the selected color-in this case, red. So it would be a field of gray, and then some sharp, contrasting black flowers where the red flowers are.
That's pretty much it for digital-there are lots of variations of these, though.
