So, I'm not the only one then. I don't see a difference either, but my laptop can barely do HD so I wasn't sure if that was the problem. Yes, only the drone is moving, but the building is moving relative to the drone.Call me dumb- but I see no difference. I use ND filters when the light is just too bright to shoot, and to create motion blur with moving objects. Of course, there are no moving objects in this this building or storefront.
Any suggestions for another test?
