Color enhancing filter.

Has anyone used one of these before? Particularly speaking of the green enhancing filter. I'm planning on getting one for photography but I've never used one before. Do they have any effect on the other colors in the picture?

To my understanding color filters change your scenes to the color
of the filter. So a green filter will create a greenish cast on your
whole scene. I don't think it does anything with just the color
green, but I might be wrong. It might also depend on different
filters etc.

So which filter specifically are you looking to get and more
importantly for what reason?

Color correction is (in my mind) much more powerful and visual
in post. Although that's primarely a personal preference, ofcourse.

Dustin,
In color video, color filters will tint your whole picture, and trick your Auto-white-balance into bizarre behaviours... You may experiment for fun.

But mainly, they are used in black and white photography to modify the contrasts. For instance, a yellow filter will make darker skies with bright clouds in B&W. A red filter goes even further for a dramatic contrast while brightening skin tones. A green filter will enlighten the surrounding grass and foliage, thus reducing the general contrast effect in B&W.
For color video, I love the polarizer filter: it reduces glares on shiny surfaces and brings life into bright colors.

I will be using this on my Canon EOS 500n slr. Here is a link to the filter I am looking at.....

it says that it does not affect the other colors but I'm curious as to whether this is true and if it is worth the purchase, or if its just a piece of crap...

Dusting: from the looks of it that filter indeed accentuates the
greens. I'm not sure how such a filter works so can't really
comment on things futher, sorry.

I am contemplating the use of filters such as Tiffen's warming filter or enhancing filter. The warming filter is "supposed to" improve skin tones while the enhancing filter boosts reds, browns and earth tones (good for scenic shots like fall foliage or the Grand Canyon).

Or, would these effects be better achieved in post?

What about grad filters for things like improved sky color and sunsets?

My guess is that it must be a sort of polarizer, which seems to enhance the colour of chlorofyl containing materials. Don't ask me how though. I think plant surfaces polarize specular reflected light, which can then be filtered out, showing the colours more clearly.
Perhaps the chlorofyl bit is a myth, but I know that plant colours appear more saturated using a polarizer.
