Circular Polarizing Filter, CPL Filter (AF Compatible) Effects: Circular Polarizing Filter (CPL Filter) is the main effect of "reflection removing" effect that removes reflections from images and light on surfaces such as water and glass surfaces, and the color contrast effect of darkening blue skies, enriching the color of trees, mountains, buildings, etc. In addition, you can use CPL filters to enhance the color of the rainbows floating in the sky, weaken or darken reflections on the water and glass surfaces, and you can use CPL filters to expand the photographic expression.

Note when using Circular Polarizer Filter, CPL Filter is not effective in all shooting situations. The effect will greatly vary depending on the light source and location of the subject and the position of the light. Try different shooting situations and enjoy your photo life.

How Circular Polarizing Filter (CPL Filter) Works: When light reflects it, the wavelength direction changes. CPL filters have the ability to adjust the wavelength that comes into the lens. The front ring of the CPL filter rotates but the rotating surface has a fine slit that only takes a specific wavelength direction. By changing the direction of the slit, only the wavelengths with a certain direction enters the lens to increase the contrast effect and eliminate reflected light.

How to use CPL filters effectively: In fact, you can see if you try to take a shot, but the CPL filter may not be hacky and it is virtually effective. The best effect is shown in the direction of the camera and the 90° direction of the sun (light source). In addition, for water or glass surfaces, the light can be removed from 30 to 40 degrees to the surface you want to remove reflections. While rotating the front ring, the effect will change depending on the angle of the sun and the object, so try a variety of different types and experience the CPL effect.
