Anyone here do long-exposure still photography with their drone? If so, how do you manage it? I watched a couple of YouTube videos on the subject yesterday and almost bought a few neutral density (ND) filters of the darker variety. I already have a set of PolarPro ND filters (ND4, ND4/PL, ND8, ND8/PL, ND16, ND16/PL); I'm referring to ND128, ND256,and ND400 filters, ones that really darken the scene to allow long exposures in full daylight.

I've done a lot of long-exposure shots using still cameras. For those, I set the camera on a tripod, compose and focus the shot with no filter on the lens, then screw on the ND filter and take the shot.

With drone photography, I won't have that luxury. I can't screw in an ND filter when the drone is 300 feet in the air.

How do you compose a scene when the ND filter is so dark you can't see much of anything through the lens?

Does the drone camera have trouble focusing when so much light is blocked?

If it makes any difference, I have a Mavic Air.
