I've been doing alot of 4k shooting and noticed the colors have been a bit washed out because of our strong sun in AZ. Of course I just mess with the contrast/brightness/saturation and that makes up for it, but I would rather just prevent it. I want to get an ND filter kit and I found PhantomFilters which are very reasonably priced and many people had good experiences with them on the DJI forum. My only concern is its not glass but I'm guessing plastic. Will this effect the resolution or quality of my 4k videos? The reason I shoot in 4k is I like to make big 3d panoramas out of the stills that are exported from the 4k video. Fast, easy and beautiful!
