Polarizers are essential filters for increasing the image quality of your outdoor photographs because they remove atmospheric haze, increasing contrast between clouds and sky. polarisers also remove unwanted reflections from water, windshields, windows, and foliage. Note: If you have a autofocus camera or a digital camera with a CMOS chip, you need a circular polariser, rather than a linear. Circular and Linear refer to the polarization of the light, not the shape of the filter. (i.e. we make square circular polarisers)
