How do you set the PL level?

For photos - you basically keep turning the filter until you find the optimum direction of polarization..
For videos - obviously that cannot be done as once the bird is in the air, the required orientation of filter changes as the direction of drone changes... Whatever is set on the ground is fixed.. Most CPL filters for drones (for video purposes) come with a marking indicating the ground orientation (For Ex- check the PhantomFilters.com CPL)..
