Actually, Litchi does allow camera adjustments at each waypoint. I haven’t been using it long, but today, I loaded Litchi Mission Hub on my pc, and positioned the camera differently at each waypoint. I also had the flight pause for 2s and turned the drone several times at a couple of waypoints, while taking photos.
I’m guessing that’s what you were talking about. I couldn’t adjust the light/contrast, but that would be asking too much, I think.
Like I said, I have been using Litchi for a very short time, so this may be a new feature.
