I was tinkering around with the camera settings on the P3S and started looking at the gimbal setting and found that I can unlock the camera view to look up 30 degrees
Its handy. Been using awhile. If near tall tree or building can look up a bit to get orientation. sure you get props but it has different colors as you bring slider down so you know when level
I think it's more for use with the FPV setting which basically locks the gimbal at whatever angle. You would need positive camera angle so you aren't staring at the ground while flying forward.
I guess you could also use it to stare at the sky while flying backwards?
