Hi
I particularly like shooting at sunsets. For those extreme dynamic scenes, 5 brackets are not enough, however, so I take 2 or even 3 AEB 5 shots with different EV settings to get a satisfying result.
My only problem: after shooting an AEB5, the drone takes about 3 seconds until it's ready to take another shot. Depending on the wind, the drone drifts too much during this time, leading to a parallax error that cannot be fixed by my software. So depending on the wind conditions, I might or might not be lucky..

Here's an example (castle Landskron) with a litte drift between the 2 AEB shots, you can see it on the flagpole if you enlarge the picture:

I created it using 2 x AEB 5 shots:
Exposures: 1/2500s 1/1500s 1/1000s 1/640s 1/350s 1/320s 1/180s 1/120s 1/80s 1/50s
HDR algorithm: debevec
Tone mapping: fattal

And here, a lucky shot with no visible double images:

Exposures: 1/8000s 1/6400s 1/4000s 1/2500s 1/2000s 1/1250s 1/800s 1/500s 1/320s 1/100s 1/60s 1/40s 1/25s 1/15s (one exposure time overlapped, so 14, not 15)
HDR algorithm: debevec
Tone Mapping: fattal

My wish for Mini 4:
- More brackets in one shot (AEB 9, AEB 11, ...) or even better: Auto AEB, where the drone takes as many AEB's as needed for the corresponding dynamic range of the scene
- or: faster time after taking an AEB shot until the drone is ready for another shot

Otherwise, the Mini 3 is perfect for me, it fits in my backpack and performs super well :cool:

well done. I have done the same kind of thing for images with such a high dynamic range.
