What filters do you guys recommend for filming? and some photography? 16 and 32? and what brand do you guys recommend?
For video mostly, to get shutter double frame rate (shooting FPS 24, aim for 1/50k shutter, 30 / 60 etc).
So for video, whatever is needed for that purpose in various light, with various backgrounds (bright sand / snow, or regular daylight, near sunrise / sunset, etc).
For photos, whatever you need for motion blur of water, car lights etc.
You don't say what drone you have (we are in the
MA2 section), but in general Polar Pro are the leaders here, costly.
You probably won't pick the difference with brands like Pgytech, Neewer, Freewell.
Usually a set like HD4, 8, 16, 32, maybe a 64 will do most for filming, if you want really slow shutter for photos you need to go higher in some cases.
Depends on what your drones settings are capable of.
