Really improves color (just be patient and rotate the filter carefully), gives much better (optical) result than image processors. You'd lose 1-1.5 F but worth it. Could even be very useful in darker environment where sporadic light sources are present. Not exactly cheap but good investment in thousand of photos. Shipping was fast. Thanks. Review: Great Value - As far as I can tell, this filter rocks for my use-case. I wanted a weaker filter for low light. I have not used one for many years, however. Nothing to compare it to. ## Features - 【Enhance Color & Contrast】CPL filter can enhance the color and contrast, and remove non-metallic reflections such as water, and glass to show the true color, especially used in white cloud and blue sky photography. - 【Multi-Coated & Cleaning Cloth】18 multi-layer coating reduces reflection, and glare and improves color saturation and contrast.
