Our CPL Filter cuts reflections, boosts colour saturation and increases contrast by cutting out polarized light. Polarized light can wash out images with silvery reflected light, which is why our CPL Polarizing Filter cuts out 99.9% of reflected light from water, glass, and non-metallic surfaces, uncovering bolder colours in your images. Rotate our Polarizing Filter to remove polarized light from any direction to improve colour saturation, contrast, and remove reflections. At full polarization, our CPL creates a 1.33 f-stop light reduction.
