The DJI Osmo Action 4 is a great camera! When following the 180 rule (your recording speed is set at double your frame rate) for your video recordings, I show the value of both a CPL and three ND filter strengths. The particular ND set I used in the video is the TELESIN 4-Pack with a CPL, ND 8, ND 16 and ND32.
