Does CPL filter really work?

[dbusguy]

My picture below shows how bad the glare on my windshield is in sunlight. The A129 seems to really pick it up and I'm wondering from those who have used a CPL filter, are they worth the money and do they reduce the glare from the dash. Center of picture is clamp to hold cell phone and you can see the defroster grills. You can see that the plate on the Jeep in front is not readable.

Yes, they work, and when reflections are as bad as that it will make a big difference.

However it does depend on the type of vehicle, for the one in your Avatar it would make no difference...

 

[jokiin]

yes they work, yes you need one

I run them on both front and rear lenses. They're like $14 each

Yep, but be ready to remove the filter each time for night use as it "eats" 1 to 2 EV.

That depends a great deal on the camera, some do much better at night than others. I've yet to have a need to remove my polarizers for night driving.

CPL work fine and are a must have, not least if you don't have a flat black dashmat.
I can not recomend to remove CPL filters at night, just leave them there if you have a modern dashcam.

I have CPL on both cameras and in my case makes a huge difference.The car is 2018 Ford Focus..

A couple of my old posts from 3 years ago showing the difference with and without a CPL.

My new SG9665XS, question about version

Reviewing videos from the last week, one thing I see over and over that I hope that can be addressed and corrected in an update is the exposure, there is washout of red and green signal lights. They always look like white lights. And the overall exposure looks a bit too "contrasty". No +/-...

Thanks for all the replies. You're all saying that it is worth installing a filter. I wanted to ask because I did search the forum and came across the quoted link and when I looked closely at the comparison photos, I noticed that there was only 1 or 2 seconds between the without and with photos. I was feeling like the photos were altered and not real because I could not figure how a filter could be installed in 1 or 2 seconds. Thank you to the actual users who have said they do work and feel it would remove the glare from my dash.

[dbusguy]

Ah. That explains it, thanks.

CPL filter, are they worth the money and do they reduce the glare from the dash.

I use the cpl filter made from 3d glasses and it definitely works. In polarized filters the angle must be adjusted correctly.
Read my share on my cpl filter below

Sun reflection problem

The 3D glasses I bought were excellent. I removed the polarized glass from the glasses frame and I checked and marked the polarized direction in an empty parking lot. I cut it in a rectangular shape with scissors and attached it to the apparatus I prepared. I will share the shooting videos later...
