For video, I mainly leave it on Auto. I don’t generally use ND filters, but do have them. Colour correction and grading is done in post. For photos, it depends on the time of day, target, etc.
The best single thing you can do to improve the quality of footage is to adjust your gimbal settings. Obviously, there are other things that you can do, but if I had to say what adds the most value … it is this.
Settings below for the Air 2:
Settings for Normal:
Pitch Speed: Low: 6 - 10
Pitch smoothness: High: Android 20 - 25 iOS: 70 - 90
Rotational Yaw Speed: Low: 20 - 50
Yaw Smoothness: High: Android 20 - 25 iOS: 70 - 90
Adjust accordingly for Sports Mode or Cine Mode!
