CPL Filter – Why You Need One for Your Dash Cam

Do you find that there are too many glares or reflections on your dash cam videos? The CPL filter helps to reduce unwanted light, brightens the colors and improves the details. A CPL camera filter improves the quality of your video, regardless of whether you are driving for short or long distances. We’ll examine how it operates and learn the importance of using it for good recordings.

CPL stands for Circular Polarizing Filter. It helps to remove shiny reflections by filtering specific light waves. Shooting your work through glass, across water or in the sun will result in clearer and more accurate colors with a CPL filter on your camera. 

Both photographers and drivers using CPL lens filters can easily improve their images. The CPL filters of Redtiger are manufactured for their dash cams, making sure they fit well and function optimally.

People often use CPL lens filter, CPL camera filter and CPL filter interchangeably. All of them describe using the Circular Polarizing Filter which reduces reflections and sharpens the image. CPL camera filter or CPL lens filter, both terms describe a way to improve the clarity of your dash cam’s recordings.

Although CPL filters are well suited for photography, they also perform well in dash cams. You may also find that they are referred to as CPL camera filters or CPL lens filters. All these terms are the same in meaning.

Understanding the workings of a CPL filter can allow you to use it more effectively. The reason there is glare on the road is that light bounces off the windshield or other shiny objects like the water. The glare in the sky can spoil the finer details in the picture and make your footage difficult to enjoy.

By filtering out extra light waves, a CPL camera filter allows the camera to see only the light necessary for a good photo. The environment becomes less bright with more contrast in colors. In practice, less reflection occurs from water on your car’s windshield or wet ground, making your dash cam’s images brighter and easier to see, both at night and in the daylight.

Using a CPL filter in your dash cam gives you several benefits. This is what you will see:

1. Reduces Windshield Reflections

No one enjoys watching videos that are spoiled by reflections on the dashboard. Applying a CPL camera filter removes the annoying glares, resulting in clear and professional videos.

2. Improves Color and Contrast

Sky, grass and road signs all become more vivid when you have a CPL lens. It improves the colors in your everyday filming, giving them a more realistic look.

3. Minimizes Headlight and Streetlight Glare

While driving at night, there is often a glare from headlights and streetlamps. With a CPL filter in place, your nighttime shots are improved and are simpler to review.

4. Improves Day and Night Video Quality
