This back and forth doesn't add anything informative to the subject, please stop.
This is however the sub-forum for the air2s. So if your experience is with other drones please mention that. Later on you did mention that but not initial, and I feel that's where the discussion started. On the Air2s there simply is no adjustable aperture. Other drones like my phantom 4 pro do have that, but even then I use ND's as a base but thats a personal pref.

Dear Jack,
thank you for your further feedback.
My name is Steffen from the technical support department. Your case was forwarded to me in order to assist with the remaining technical questions.
The lens distortion, dark corners, dispersion is an objective physical phenomenon. So there will be a difference between the brightness of the lens corners and the brightness of the center of the lens. This difference will aggravate the noise after correction through the algorithm, our R & D team is constantly optimizing this algorithm to reduce the noise.
A ND filter is used in a strong light environment to reduce the amount of incoming light.
Then if camera is in a normal light or weak light environment, and the lens parameters are unchanged. We just add the ND filter, the noise will not increase.
But if Camera is overexposed , then the ND filter will reduce the amount of incoming light and then cause more noise after correction." |
