Ever wonder what a polarizing filter is and what it does? In this video, we are taking a look at a couple of polarization filters also knows as CPL’s for the GoPro Hero 5 Black and Hero 6 Black. These will also be compatible with the GoPro Hero 7 Black which will be released later this fall.
What Is A Polarizing Filter For Your GoPro
A polarizing filter is a filter that attaches to your GoPro and its purpose is to cut back reflections from shiny surfaces such as water, metallic surfaces, glass, even plants, and paved roads. When reflections are minimized your GoPro can capture deeper more true to life colors with more saturation and vibrancy. Filming on water is a perfect scenario. The glare from water can really desaturate the video or photo you take. By adding a polarizing filter the camera can record richer blues in the sky and the water itself. It can also in some situation make the water more transparent so you can film what lies beneath. Another good example is when filming yourself driving with your GoPro. If you have a GoPro mounted on a car on a bright day, the asphalt can be quite shiny. Using a CPL will cut back the glare on both the vehicle and the road leaving you with a beautiful video with deep vibrant colors. Myself I even use one when taking photos of my garden. Plant leaves can have a sheen on them. Using a CPL allows me to capture all the beautiful colors of the flowers easily.
TIP: In order to use a polarizing filter you must use it 90 degrees to the sun. So filming with the sun directly in front of you or behind you will have no polarization advantages when using a CPL with your GoPro.
What CPL Filter Is Right For You & Your GoPro
There are many CPL filters on the market for your GoPro, In this video a take a look at two. The first filter is by SandMarc which has a rotating dial that sets the polarization. The second one by Telesin has to be removed and rotated to set the desired polarization. I have used both extensively and I have found that both provide similar results with the quality of footage that is produced. The SandMarc filter is easier to use as you can just dial and rotate the filter to get the appropriate polarization, whereas the Telesin CPL must be removed and rotated manually. There is a large price difference between the two the SandMarc CPL runs about $39 and the Telesin comes in at $12. Even though its cheaper the Telesin polarizer filter also includes a lens cap to help protect the lens for smudges and scratches. One other nice feature the Telesin brand has is the ability to lock the lens on the GoPro via an Allen key and screw. This is important as the large lenses have been known to fly off when being used at high rates of speed, the wind velocity can work the lens off. There is no way to tighten the SandMarc polarizer filter. Just keep in mind over tightening the screw can leave marks on the GoPros finish.
Watch our demonstration video where we show you how to use and install these polarizing filters on your GoPro. We also include some sample footage showing you the difference of using a polarizing filter and not using one.
Currently, the Sandmarc CPLS are on Backorder I will add a link to it when it’s available.
