It doesn’t matter if you turn off the 30 degree feature on the P4 to allow you to gimbal up. The Pano feature will still raise the camera way too high and you are going to get props in every top shot.
I have tried even starting with the gimbal pointed down, and it just centers and goes through the routine.
I have used the Pano feature on the Spark and Mavic, and love it on the Mavic since you can usually get by without a lot of props showing. Plus the Mavic is the only drone that allows rotation of the sensor (not gimbal) to Protrait orientation, which is actually better for a pano since the retrofocus distortion of the lens will not come into play as much. I would love to see this with the P4 and hoped that it would be added to the P4 Vr 2.0, but it wa not.
On the P4, the props are going to show. And usually a lot. I agree you can take the time to remove them with features like Content Aware since they are usually in the sky, however this forces you to take the raw dng to a tiff, and move to photoshop, and thus stitch the pano from photoshop as a tif, I prefer to stitch to a larger DNG and thus stay in raw. Lightroom’s ability to remove the props with it’s tool set is much less acceptable than content aware in CC
Now I usually just manually take the Panos, But it’s not really possible to correctly lineup the 9 shots, but you can get close.
The other issue is the huge amount of retrofocus distortion the P4 lens has which is increasingly made worse as you look down. You will see this with any straight object towards the edge of the lens, which will both bend and shorten and fatten due to the distortion. Such distortion is common in all wide angle lenses, but the P4 is pretty strong. And there is barrel distortion that you can somewhat correct in Lightroom, however the I find that the default lens correction is too strong and prefer the one for the Inspire 1.
