Did some more testing today with the P4P. I've updated with the app update (Jan 17) that fixed the white balance issue and I've made sure that I have the latest firmwarre updates for the drone and remote control. First two missions went great with auto settings for imagery.
Changed battery and flew again. Started mission, but drone didn't start taking photos. Flew about 100 feet, then just stopped and hovered. Had to cancel mission by clicking "home" button.
I landed and started over with a new mission. Before it got to the starting point, I noticed that the white balance was "blue" again. It was late in the day, on a cloudy day and I think it seems like it sets the white balance while the camera is still looking at the horizon, then points the gimbal downward. I started over again.
This time I manually set the camera settings in the DJI Go app (took off around 200 feet, look down to get the right setttings). Then I re-flew the mission. This time it worked great.
In the past, I've had good luck with DD being consistent. We are looking to scale drone operations at our organization and the inconsistency in operations is going to cause concerns problems for our new users. Any help or advice you have would be greatly appreciated.
