One thing the other answers have missed is that a CPF reduces the light by two stops and so can be used as a neutral density filter if needed.

I have a Nikon D7000 Camera and just recently purchased a Poloarized Filter for 18-105 zoom lens. I know to use the filter when there may be a glare from an object, but would you suggest to use the filter on cloudy days?

Objective is to get a richer or deeper amount of color from the sky and objects.

Thanks

Many people forget that a CPL will have an effect with colors, also. Yellow, for example, can be intensified with a CPL. Works great when doing 'fall colors'. DJT

I utilize a polarizing filter when out shooting on the water decreases the glare

You can use a CPL on a overcast & rainy day. In Bryan Peterson book "Understanding Exposure" He shows how to use a CPL shooting a waterfall & stream on a overcast rainy day. It removed the reflection & dull gray glare from the surface of the water. Being dark he needed a small aperture f/22 with a long exposure 1 sec to get that cotton candy look from the falls. He was able to get 2/f stops of light reduction with his CPL. Have used myself with good results. There is a wealth of information in his books.

:thumbup: I second that. I've used polarizers on many occasions to remove foliage reflections and intensify colors on rainy/cloudy days. Very effective.

All said above is true - one minor point It is a POLARISING filter the effect after using it is Polarized.

I have found that under many light conditions a CPL will increase the definition of green leaves, I guess it reduces the scattering of light.

You are right, but no longer using as a CPL, but as a ND filter. A two for.

Two for one works for me. With todays digital & PP software many filters from the film days are not needed. But a good CPL is the one every photographer should have there camera bag. If all you ever used it for was to make blue skies bluer it would be worth it.

Hey Red Baron. I love my polarising filter for lots of applications, including fungus shots which are often in low light, but they result in a deeper hue if the subject has a shiny surface. For water scenes & other landscape shots I nearly always take photos both with & without the filter, (just by turning it, not removing it) because when I look at them on my computer I sometimes prefer the unfiltered appearance eg the shimmering surface of a lake. As everyone else says, it is fun to experiment.
