Promasters HGX CPL Filter

I just recently purchased a Promaster HGX circular polarized filter. The reason for my purchase.....I wanted to get that awesome blue sky I see in every professionals landscape photo!!! The circular polarized filter only allows certain light rays through and cuts down on reflection of light rays on surfaces such as water and glass. This filter makes blue skies look bluer and provides better contrast for colors in general. Here is an example of a photo that I took using the CPL Filter. This is a picture of Kim at Kezar Lake Maine.
