I ordered the three pack of Polar Pro filters for my P4 and got the Polarizer, ND4 & ND8. I did a comparison flight video programming the flight with the regular filter, polarizer, nd4 and nd8. The file is so big and I am traveling I can't upload it right now but I had the same issue. Check this video out yesterday I did with the ND4 and see the "artifacts" or "fuzziness" I am getting. What am I doing wrong? This last flight was actually my third battery flying and it may have got a little too dark but it was right at Dusk and that was the filter I thought I needed to be shooting with. I was shooting at 4k @ 30fps in auto mode. Any help or suggestions on why I see all these little artifacts and fuzziness? Even my shoot during the bright day had the same issue.
