I posted a 'me too' because I view this as a software/design issue, not a operator/operations issue.
Yes, I aimed at the brightest part, no I did not set manual exposures.
There are two schools of thought on the term Enterprise - aka business or professional.
One being, if you are buying expensive tools, you should know how to use them, and spend the time to dial things in just right.
The second being, if you are a professional, time is valuable, and the extra investment in a supposedly professional tool should make it work, consistently and repeatably with little input from the operator.
I'm very much of the second school of thought. The pano function on the E2E is surprisingly slow, and the extra time of setting exposures is an unexpected surprise. All of this kills precious battery time, not to mention time on site. I respect immensely the attitude that UAVs are flying cameras and should be treated and operated as such, but my view is that it is a flying survey rod (which happens to do a bunch of other fun things while it is in the sky).
At this point, it is going to be faster and more efficient for me to bring my Parrot Anafi along on projects requiring panos, because it 'just works' out of the box.
