The Vivid Collection for the DJI Mini 4 Pro was designed to combine two filter effects (Neutral Density + Polarization) into a single glass element. The collection includes ND8/PL, ND32/PL, and ND128/PL filters, which will give you full coverage from golden hour to mid-day sun. To achieve the effect of an ND16/PL filter, simply use the ND32/PL and bump your ISO up to 200. This will allow you to omit constant filter changes and reduce the amount of gear you need to purchase because ISO 100 and 200 are perfectly clean on the Mini 4 Pro.
