CPL issues

Double H · Mar 17, 2021

Hopefully some of you expert drone pilots and photographers can help me out. Whenever I use a CPL filter with my mini2, I get darkness in the lower left and right of the picture or the video as seen in the picture below. In this instance, the sun was 90 degrees to my left. I cant seem to eliminate those dark areas no matter which way the drone is pointing in relation to the sun. Any help or tips is appreciated

That's not a result of the polarising.
It's called vignetting and is caused by the filter frame extending too far and blocking some light around the edges of the image.

As Meta4 has said that does look a lot like vignetting to me.

You get the same problem on DSLR cameras if you stack too many filters, or use a lens hood with a wide angle lens.

The only answer is to try to fit the filter closer to the lens, or use a different filter with a thinner frame.

What brand of filter you use? If your filter is well fitted on the camera lens and you insist to use the same filter the only tip to avoid it is to do some digital zoom.Mini 2 has digital zoom.
